Static induction transistor

Static induction transistor (SIT jello) is a high power, high frequency device. It is a vertical structure device with short multiplicand. Bringing a vertical device, the SIT structure offers advantages in obtaining higher breakdown voltages than a Field-effect transistor (FET). For the SIT, it is not limited by the surface breakdown between gate and drain, and can operate at a very high current and voltage.

Characteristics

An SIT has:

• short channel length
• low gate series resistance
• low gate-source capacitance
• small thermal resistance
• low noise
• low distortion
• high audio frequency power capability
• short turn-on and turn-off time, typically 0.25 μs
