In power electronics, the SCR, DIAC, and TRIAC are three common semiconductor devices that are very useful in electric power control and conversion applications. Though they all belong to the thyristor family, their operation, structure, and applications differ significantly. Here’s a detailed explanation of SCR (Silicon Controlled Rectifier), DIAC (Diode for Alternating Current), and TRIAC […]

Piezoelectric Transducer – Construction, Working and Applications
The term “Piezo” in Piezoelectric Transducer originates from the Greek word piezein, meaning “to press” or “to squeeze.” This etymology reflects the fundamental principle of piezoelectricity—a phenomenon in which mechanical pressure generates an electrical voltage. Piezoelectric transducers (sensor / Actuator) harness this effect to convert mechanical energy (such as pressure, force, vibration, or acceleration) into electrical […]
Constant Current Diode Symbol, Construction, Working & Applications
Constant Current Diode (CCD) (also known as Current Regulator Diodes, or simply CRDs) are unique semiconductor devices designed to maintain a constant current over a wide range of voltages. They are extremely useful in circuits where a stable and predictable current is crucial, regardless of voltage variations. In this article, we will cover the Symbol, […]
Astable Multivibrator Circuit Diagram, Working and Applications
An Astable Multivibrator is an essential oscillator circuit in electronics, used to generate continuous square wave signals without any external triggering. It is called “astable” because it has no stable state — both transistors in the circuit keep switching ON and OFF alternately, producing a continuous flip-flop output. In this article, we will explore a […]
Avalanche Diode Symbol, Construction, Working & Applications
The avalanche diode is a specialized type of semiconductor diode designed to operate in the reverse breakdown region without getting damaged. It plays a critical role in protecting electronic circuits from high voltage spikes and is commonly used in voltage regulation and surge protection applications. This article explores the avalanche diode in depth, from its […]
Fast Recovery Diode Symbol, Construction, Working & Applications
Diodes are semiconductor devices that allow current to flow in only one direction. They are widely used in modern circuits for applications such as switching, rectification, and protection. Among the various types of diodes, the fast recovery diode (FRD) is specifically applicable in high-frequency applications due to its fast reverse recovery time. When a diode […]
