Is FET gate protection required?

Latest Updated:04/01/2007

Question:

Is FET gate protection required?

Answer:

The protection diode embedded between the FET gate and the source serves to protect against electrostatic damage during handling.
If there is a risk of the rated voltage being exceeded in the circuit that is actually used, insert a gate protection circuit such as a constant voltage diode.

Caution The characte s of the RF & microwave devices may degrade if a diode for gate protection is connected.
