I’ve heard a lot about voltage clamping on MOSFETs. I’ve read some material online but still don’t have a good understand the purpose and when you would clamp the voltage on a MOSFET or why? When/why do you Clamp the voltage on a MOSFET, are there other types or circumstances of clamping like current clamping, etc? Can someone explain it or point to a good resource when I can go learn better?

 

Mosfet gate voltage clamp - please see the first post and #3, especially the zener and R2 in the circuit.
