i would like to protect a 3 mosfets and 3 leds connecting to this mosfet from over voltage or transient voltage spikes.
Attached is a scheme with a capacitor in paralel prior each mosfet.
vin = 12v from regulated wall adapter, vload =12v, 2A each load, load is a led. mosfet i am using is FDMA430NZ.
Mcu to gate 5v, 25ma max.
Apreciate for any advice for determining the capacitors values so they will be efective in protecting? or is a 0.1uf is the right value base on these details?
What If i will use a tvs diode instead of the diode in beginning of the circuite, will it cover all this circuite protection for over voltage spikes?
