hey guys,
i have a circuit setup, which is just a big magnet that is switched on and off using a MOSFET and a TTL signal. My problem is, due to the high inductance (~2400H) I am burning out my mosfet. What is a reliable way to stop this? Diode across the mosfet?
Here's a quick and dirty circuit schematic
The resistor and the inductor simulate the magnet and the resistor and diode in parallel makes sure i get clean magnet pulses when i shut off the magnet.
