SUS full form

What is the full form of SUS?

Answer :

  • Silicon Unilateral Switch 

What does SUS mean?

A SUS is similar to a PUT  but with an inbuilt low voltage avalanche diode between gate and cathode as shown in the figure. 

Because of the presence of diode, SUS turns on for a fixed anode to cathode voltage, unlike an SCR full form silicon control rectifier whose trigger voltage and/or current vary widely with changes in ambient temperature. 

SUS is used mainly in timing, logic, and trigger circuits. Its rating is about 20 V and 0.5 A.
