Important characteristics of SIT

Important characteristics of SIT (Static Induction Thyristor)

Symbol of SIT

1. Switching speed : 1 to 6 µS
2. Voltage rating : upto 2500 V
3. Current rating : only upto 500 A

• The biggest disadvantage of SIT is that it is extremely sensitive to the perturbations in the manufacturing process.
• Small variations in the manufacturing process can change the device characteristics to a great extent.
• The biggest advantage of SIT is its very short turn-on and turn-off times (typically 0.25 micro-seconds).
• The other advantages are : low noise and low distortion.
