Hi internet
got a slight problem. To keep things simple, I have 3 parts. Resistor, capacitor and a transistor arranged like this:
Very simply, all it does is once the capacitor is full, the transistors emitter collector or drain/source resistance becomes zero.
for safety reasons, the transistor needs to have a break down voltage of 400v+. It also needs to be able to handle 10 amps @ 100 degrees Celsius.
List of problems:
Unless there is anything else out there that I have not educated myself into? Thyristor?

List of problems:
- cant use N channel mosfet, unable to get the gates voltage above 250v to keep it on.
- seaching for P channel mosfets proves to be difficult.
- Cant use IGBT, same problem as the N channel mosfet, unless there is a P channel version
- Using NPN/PNP means power loss of 5w or more. Furthermore, its hard to find a high voltage, high amp PNP/NPN with high gain 100 or more
