TRIAC – Operation, symbol, circuits & applications

A TRIAC or TRIode for Alternating Current is a three-terminal bidirectional thyristor, meaning that can conduct current in both directions when activated properly. It is used in AC switching applications. It can be considered as two SCRs connected in antiparallel. Unlike a silicon-controlled rectifier, it is capable of conducting positive and negative cycles of electric … Read more

Thyristors and their types

Thyristors are high-speed semiconductor switching devices that are made up of four layers of alternating p and n-type materials. They are used in AC/DC switching and AC power control applications. The thyristor symbol is a diode symbol that has three terminals, the gate, anode, and cathode. Silicon Controlled Rectifier (SCR) Silicon Controlled Rectifier (SCR) is … Read more

SCR – Silicon Controlled rectifier

A Silicon Controlled Rectifier (SCR) is a unidirectional semiconductor device that can be triggered into conduction by applying a positive gate current. It led to tremendous advancements in power semiconductor devices. They are also known as phase-control thyristors. They are high-speed semiconductor switching devices, similar to Shockley diodes but with an extra terminal. They generally … Read more
