The Diac is basically a two-terminal device. Here we will discuss the symbol, construction, VI characteristics, advantages, disadvantages and applications of Diac. It is such a combination of semiconductor layers that allows triggering in both directions. The Diac is used as a triggering device for the TRIAC circuits. What is a DIAC? A DIAC (Diode […]
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.
The VI characteristics of SCR (silicon-controlled rectifier) is a graph of anode current Ia on the y-axis and anode to cathode voltage on the x-axis as shown in the graph. It describes the relationship between the voltage across the device and the current flowing through it. The characteristics in the reverse direction (anode to cathode […]
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
