Difference Between SCR, DIAC and TRIAC

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 […]

Shockley Diode Symbol Construction, Working and Applications

You can see Shockley diode symbol it is a four-layer (P-N-P-N) semiconductor device. Like pn junction diode It conducts in forward bias and stops conducting in reverse bias. The main difference between a conventional diode and a Shockley diode is, it starts conducting when the forward voltage crosses its breakdown voltage. It is an active component. It […]
