There are many basic electronic components used to build electronic circuits. Without these components, the circuit design is never ready or has not worked properly. These components include resistors, diodes, capacitors, integrated circuits and so on. Some of these components consist of two or more connectors glued to the circuit boards. Some may be packaged types, such as integrated circuits that contain different semiconductors. Here is a brief overview of each of these basic electronic components and you can get detailed information by clicking on the links for each component.

Basic electronic components

Electronic components are separate basic units for use in any electronic electronics system that has different domains. These components are the basic elements used for the design of electrical and electronic circuits. These components have at least two connectors used to connect the circuit. The classification of electronic components can be done, for example, on the basis of active, passive and electromechanical applications.

The most important electronic components

The design of the electronic circuit takes into account the following:

Basic electronic components: capacitors, resistors, diodes, transistors, etc.
Power supplies: Signal generators and direct current sources.
Measurement and analysis equipment: cathode ray oscilloscope (CRO), multimeters, etc.

Active components

These components are used to amplify electrical signals to produce electricity. The operation of these components can be done as an electrical circuit in the electrical equipment to protect the voltage and current. The active component performs its function because it is controlled by a power supply. All of these components require a power source, which is usually removed from the DC circuit. All high quality active components include an oscillator, an IC (integrated circuit) and a transistor.

Passive components

Components of this type cannot use the power supply of an electronic circuit because they do not depend on a power supply, except for those available in the AC circuit to which they are connected. As a result, they cannot amplify even if they can increase the current, otherwise the voltage or current. These components mainly include bidirectional connectors, such as resistors, inductors, transformers and capacitors.

Electromechanical components

These components use an electrical signal to make some mechanical changes, such as rotating the motor. Typically, these components use an electric current to generate a magnetic field so that physical movement can occur. Different types of switches and relays can be used in this type of components. Devices that have both an electrical process and a mechanical process are electromechanical devices. The electromechanical component is used manually to produce electricity by mechanical movement.

Passive electronic components

These components can store or maintain energy in the form of current or voltage. Some of these components are discussed below.

Opponent

A resistor is a bipolar passive electronic component used to resist or limit current. The resistor operates according to the principle of Ohm’s law, where “the voltage applied to the terminals of the resistor is directly proportional to the current flowing through it”

Basic electronic components, the operation of which depends on an external power supply, are called active components. They can amplify signals and / or process signals. Some active components are transistors, integrated circuits.

Transistors

A transistor is a nonlinear semiconductor. The transistor is considered one of the most important devices in electronics. The transistor has changed many aspects of human life. Transistors have two main functions, which amplify the input signals and act as semiconductor switches. The transistor acts as a switch when used in the saturation or interruption interval. Amplifies signals when used in the active area. It offers a very high input resistance and a very low output resistance.

Transistors are classified according to the structure of bipolar transverse transistors and field effect transistors.

Transistor symbol

The most popular and commonly used transistors are BC547, 2N2222. Below are some common transistor packages:

A metal oxide semiconductor field effect transistor (MOSFET) is a semiconductor device that differs in structure from a bipolar junction transistor, although the applications are the same as coupling and amplification. It has four terminals such as Drain, Gate, Source and Body. The chassis is short-circuited to the source socket. The gate is insulated from the pipe next to a very thin layer of metal oxide. Therefore, it offers a very high durability compared to BJT.

By checking the gate voltage (VGS + ve / -ve) of the channel along which the charge carriers (electrons or holes) flow from the source to the channel, the width can be checked. P-channel MOSFET has a P-channel area between the source and channel, and N-channel MOSFET has an N-channel area.

The advantages of MOSFET over BJT

  • Very high resistance to entry
  • Reduced opposition to the state
  • Reduced energy losses
  • High operating frequency
  • Transistor operation
  • Transistor operation
  • Use of transistors (BJT / FET)

Amplification of analog signals.

Used as replacement units in SMPS, microcontrollers, etc.
oscillation
Overvoltage / undervoltage protection
signal modulation and demodulation circuits.
Current control in converters and chargers (high power transistors)
Types of transistor packages

For BJT and MOSFET packaging, the transistors are available in orifice (DIP) and SMD versions. for example, DIP: TO-92, TO-220 and SMD: SOT23, SOT223, TO-252, D2PAK.

Transistor selection parameters

When selecting a transistor in any user of the circuit, consider the following parameters

  • Maximum collection current (Ic)
  • Maximum collector voltage (Vce)
  • VBE voltage
  • Saturation Vce (village) tension
  • Current gain, hfe / ß
  • Input resistor
  • The first answer
  • Reverse distribution voltage
  • Maximum return current.
  • Evaporation of force
  • Interface temperature
  • size
  • Switching time / frequency

Integrated circuits

An integrated circuit (IC) is an electronic circuit embedded in a semiconductor board, which is usually silicon. This disk has millions of compact transistors, resistors and capacitors connected to metal strips. ICs are powered by an external power supply for operation. ICs perform certain functions, such as data processing and signal processing. The physical size of an IC disk is very small compared to discrete circuits, so it is called a microchip or just a chip. Due to its small size, the IC has low power consumption.

Many security-related systems that will use electromechanical technology or Solid-State electronics now use programmable electronics.

IEC 61508 covers functional safety of safety-related systems using programmable electronic and / or electronic (E / E / PE) technology. This standard applies to this system regardless of their application.
Examples of systems related to E / E / PE safety using electrical (or electro-mechanical) technology are interlocking guards and emergency stop systems for machines.

Functional safety

Devices such as programmable controllers, programmable logic controllers (PLCs) and digital communication systems (eg bus systems) are part of this trend.

Examples of applications include safe load indicator cranes, variable speed drive motors used to limit speed for protection, systems for interlocking and controlling the exposure dose of medical radiotherapy machines, or indicator lights, anti-lock braking, and engine management systems in cars. Other examples are emergency shutdown systems at hazardous chemical plants, railroad signaling systems and Fly-bywire operations. Surface flight control aircraft are the latest developments including network-based security systems, often facilitated by internet technology.


An exampleis Remote Monitoring, operating or programming from a network-enabled water treatment plant. E / E / PE safety related systems cover all parts of the system needed to carry out safety functions (ie from sensors, through logic control and communication systems, to final actuators, including critical actions from human operators). An E / E / PE system may be related to safety even if it does not have direct control over potentially dangerous equipment. For example, information-based decision support tools might be related to safety if erroneous results affect safety.

IEC 61508 as a basis for other standards Sections 1, 2, 3 and 4 of IEC 61508 are IEC’s basic safety publications. One of the responsibilities of the IEC technical committee is, wherever practical, to utilize this part of IEC 61508 while preparing their own sector or product standards that have E / E / PE related to safety systems within their scope.

Electronic Systems and Electronic Control Systems


For more details see IEC Guide 104, the preparation of safety publications and the use of basic safety publications and group security publications and ISO / IEC 51 guidelines, the safety aspects of the guidelines for their inclusion in the standard. IEC 61508 is the basis for published nuclear sector standards. It is also currently being used as a basis for developing other sector standards (for example machinery, processes) and Product standards (for example the propulsion system). Therefore it affects the development of E / E / PE related to the safety of systems and products in all sectors.


Many IEC 61508 requirements, especially in sections 2 and 3, are not repeated in the application sector or product standard but are referenced instead. The result is that most users will need IEC 61508 too.
The market for each product, component, or subsystem that complies with IEC 61508 has huge potential because in principle they are able to meet the sector standard requirements based on IEC 61508.
