Help with mosfet circuit needed

Status
Not open for further replies.
yea, this is frying my brain,

I dont have a huge budget to keep buying loads of different fets to try. i will probably pick up the 2 i mentioned earlier and the 2 i ave just found,

with the system, the trigger needs to be activated fast but the braking needs to work instantly.

the capacitor in the circuit charges up and discharges onto the P-fet to activate it faster.

i think the N-fet i selected will do the job, i just need a P-fet which activates super fast when the gate obtains a voltage on it.
 
choice of fets i have are:

1st prototype used :

N channel - IRFZ48NPBF
P channel - IRF4905PBF

then i have these:

N channel - STP75NF75
P channel - SPP80P06P

or

N channel - STP75NF75
P channel - STP80NF03L
