Hi,

I am trying to find a replacement a current MOSFET ( ZXMN3A14FTA) with a Max Vgs =+/-20V, but I have found an Equivalent Substitute with Max Vgs = +/-12V. I don't think it would be an issues, but just wanted your thoughts or someone has any other ideas regarding picture below.
Thanks,
WJ

If Vgs,will never be over 12V, I think you'll be fine. You can add a protection Zener Diode (10v) if you are concerned about higher voltage spikes. This is a very common solution to limit gate voltage. Don't forget a current limiting resistor.
