Hi people,
I want use a n-Mosfet as switch with drain connected to 95 VDC, a Load resistance of 5 ohm connected to source and the other pin to gnd.
The gate is operated by a PIC ( 5 V ) throught a NPN transistor.
The Mosfet I intent to use is the IRF 3415, but I´m not sure it´s ok.
Question 1 - How to verify if it´s the correct mosfet Using datasheet elements ?
Question 2 - Assuming that VGS = 10 V ( when PIC output = LOW -> NPN transistor in cut-off region) the Source voltage should not be nearby 95VDC? If it's correct we have another issue related with VGS max = +/- 20V ( data sheet parameter ).
Does any body help me ?
Thanks
Af
