Hacks of Electronics
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 […]
The SCR has only two states of operation i.e. it can be either fully ON or completely OFF hence SCR can as a switch. There is no “active” region of operation like a transistor.
Silicon Controlled Rectifier (SCR) is one of the oldest four-layer solid-state power device it was invented in 1957. SCR has the highest power handling capacity in comparison with other semiconductor devices. It has three terminals namely anode, cathode, and gate
