I'm newbie in electronics looking for an advice on how to properly limit gate voltage for BUZ11 MOSFET in my PWM regulator for a DC motor. Currently I'm using it with 12V power supply and it works OK, but I want to use it with 25,2V (LiPo 6S), so the gate voltage should be limited to < 20V. Thinking about Zener diode 1N4745A (16V). Will it work for schematic below?

UPD I'll also use 78L12 LDO to power NE555.
