Hello
I am new to reverse voltage protection with mosfet, I'm still studing the theory, I need some help with the maximum VGS(voltage between gate and source), I have the P-Mosfet FQPF47P06, with a maximum VGS of +- 24 volts.
There's no graph int the datasheet, so I do not know if this value is linear or not.
If I am correct, with an aditional 12 volts zener, the circuit will tolerate 36 volts maximum(theory) and if I replace the zener with a 24 volts zener, will it handle a maximum(theory) of 48volts ?
My question is, is there a rule of thumb, like use only half of the maximum VGS ? or can I use the theory(withou considering transients) ?
