P channel mosfet with esp32

See answer #3 in this thread:

Protect P-channel MOSFET from high Vgs with a zener diode?

I have a circuit for driving things like motors: [image] I have had a report ( MOSFET Vgs(max) · Issue #21 · nickgammon/arduino_sketches · GitHub ) that this will fail if the supply voltage exceeds VGS(max) for the MOSFET (it doesn't in this particular case, but in principle). On the linked page is a suggested amended circuit involving a zener diode and a couple of resistors. Does this look sound? It seems to me that perhaps the current through the zener is too low, but I might be wrong. Th…

And change R1 to 1k for the 42V supply.
