I'm designing a MOSFET (FQP30N06L) circuit to drive a (50V, 3.4ohm) pinball solenoid controlled by a PWM pin on an Arduino DUE:
The MOSFET gate and solenoid are tied to the terminal block to make external alterations easier. My concern is that, while altering the circuit I will forget to ground myself, and fry the MOSFET. My understanding is that when MOSFETs fail for this reason, they often become shorts which would fry the solenoid coil very quickly.
My question is, what can I do in-circuit between the terminal block and the MOSFET to protect the MOSFET from ESD?
