Hi,Are you sure that's how the 100mΩ is wired? It would make sense as a current-sense resistor if it were between source and ground.
How is the gate voltage being switched? D2 has no clear purpose unless it is in parallel with a gate drive resistor to speed up the gate discharge.
Hi,Hello there
Once a MOSFET is switched on, it will not switch off again even if the voltage is removed, because the parasitic capacitance between gate and source (1nF to 5nF typical) will store charge and will maintain the gate-source voltage even when the signal is removed. To remove this charge quickly, a resistor is required in parallel with this capacitor.
Yes, 100 milli ohmBut it's only 0.1 Ω! (little m = milli)
That is a description of R8, not R10.Once a MOSFET is switched on, it will not switch off again even if the voltage is removed, because the parasitic capacitance between gate and source (1nF to 5nF typical) will store charge and will maintain the gate-source voltage even when the signal is removed.

I was trying toI may not be agree with your reason !

Good point; although a person clueless enough to do that probably shouldn't be playing around with electricity...Why do I suspect that someone saw a notation that a MOSFET with 100mOhm on resistance was required, and they put it in the schematic as a resistor?
