Electric circuits are the backbone of modern technology and incorporate diverse components. Two primary categories taking center stage are passive and active electronic components. Passive components, like capacitors or resistors, interact with the electrical signals without a direct power source.

In contrast, active electronic components stand out for their ability to deliver and absorb electric power. This unique characteristic sets them apart, making them indispensable for various applications.

In this exploration of active electronic components, we will examine their distinctive features, applications, and benefits. Let’s get started!

What are Active Electronic Components?

An active component is made using semiconductor materials like silicon and germanium. It amplifies, switches, or modulates signals and plays a dynamic role in electronic systems. Examples include transistors and integrated circuits.

Key features of Active Electronic Components

Here are some key features of active electronic components:

Energy Delivery: Active electronic components can supply energy to the circuit, ensuring a dynamic role in the flow of electrical power.

Energy Production: They can generate energy from voltage or current, allowing active participation in creating and transmitting electrical signals within the circuit.

Power Gain: They also act as amplifiers, amplifying the strength or amplitude of signals, thereby providing power gain to enhance the circuit’s overall performance.

External Source Dependence: An external source is essential for their operation, highlighting their need for an external power supply to function effectively in the circuit.

Types of Active Electronic Components

Let’s look at some electronic components types:

Integrated Circuits

ICs are electronic devices having hundreds or millions of interconnected transistors, diodes, etc. Their integration enhances performance, reduces power consumption, and simplifies circuit design, making them integral to modern electronic devices. ICs find extensive use in diverse applications, ranging from microprocessors in computers to amplifiers and signal processors.

TPS63030EVM-417

TPS63030EVM-417 is a highly versatile power module that meets diverse energy needs. With an extensive input voltage range from 1.8V to 5.5V, it adapts seamlessly to various power sources like single-cell Li-Ion batteries and USB power. The output voltage can be adjusted from 1.2V to 5.5V to accommodate various devices and applications.

Diodes

Diodes have two terminals and enable current flow in a single direction. They comprise a junction between positive (p) and negative (n) semiconductor materials. The n-type region holds excess electrons, while the p-type region has surplus holes.

Electrons move from the n-type to the p-type due to concentration gradients. They allow current flow in one direction and help rectify alternating current (AC) into direct current (DC).

DST40100C

The DST40100C is a Schottky diode with a fast recovery time (<500ns) and a max DC reverse voltage of 100V. It is made for rectifier arrays with a 20A current rating, TO-220-3 package, and common cathode configuration and operates from -55°C to 150°C. Forward voltage is 750mV at 20A; reverse leakage current is 1mA at 100V.

STPS20L40CFP

The STPS20L40CFP diode is an ideal choice for low-voltage, high-frequency operations. With a 40V repetitive peak reverse voltage (VRRM) and a robust design in a TO-220FP package, it handles up to 20A (IF(AV)), ensuring efficient power management. The low forward voltage drop (VF) minimizes power loss, and its high switching speed enables ultrafast recovery, reducing losses at high frequencies.

Transistors

Transistors employ n-type and p-type semiconductors with base, collector, and emitter terminals. They serve dual roles as signal amplifiers and binary switches in digital circuits. Common transistor types include BJT and FET.

The former (BJTs) has three semiconductor layers and terminals: base, emitter, and collector. On the other hand, field-effect transistors (FETs) control current with electric fields and have terminals named source, gate, and drain.

BSZ110N08NS5ATMA1

The Infineon Technologies BSZ110N08NS5ATMA1 is a high-performance N-channel MOSFET from the OptiMOS™ series. Tailored for Discrete Semiconductor Products, it boasts an 80V voltage rating and a robust 40A current rating. Its operational temperature range is -55°C to 150°C, ensuring reliable performance across diverse applications.

Passive vs. Active Electronic Components: The Difference

Let’s look at this overview of the difference between Passive and Active electronic components:

Power Gain

Active Components: Active components, like amplifiers, can amplify power. They can increase the strength or magnitude of signals, providing power gain.

Passive Components: These cannot amplify power.

Function

Active Components: Being nonlinear and bilateral, they exhibit complex behavior responding to varying input conditions.

Passive Components: Linear and unilateral, meaning their response is directly proportional to the applied stimulus.

External Source

Active Components: Active components typically require an external power source to control and actively manipulate signals within the circuit. For instance, transistors need an external biasing voltage.

Passive Components do not require an external source to actively control power in the circuit. They respond to the applied signals without the need for additional external power.

Capability

Active Components: Actively generate and control electrical energy.

Passive Components: Do not actively generate or control electrical energy.

Applications of Active Electronic Components

Let’s look at the applications of these electronic components:

Amplification in Audio Systems

Active components like transistors and amplifiers amplify weak audio signals, enhancing sound quality in speakers and audio systems.

Oscillation in Oscillators

Active components are also utilized in oscillators to generate continuous waveforms, which are essential for various applications, such as clock signals in electronic devices.

Power Supply Regulation

Voltage regulators are also active components that control and stabilize the output voltage in power supplies, providing a stable and reliable power source for electronic devices.
