knowing that you often take parts way beyond their specs, I would like to use your wisdom.
I need a high-side controllable switch capable of charging 5pF to 400V and maintaining most of that charge for a good fraction of a second. Not important if it is a PMOS or a PNP transistor. Could you please recommend me a part known for a particularly low leakage current? Or should I use any transistor and a diode in series with the collector? A diode-connected transistor perhaps?
T_MAX is, say, 50 degrees Celcius and there will be no self-heating. The lower the leakage the better.
