I'm working on a project where I need to be able to implement a switch capable of turning ON/OFF current flow in a high voltage circuit using a very small base voltage.
The current flow that I need to control will be between 500V-2000V (~10-15mA current) and the base voltage that I would like to control that flow with will be only 3.3V (10-20mA current).
I've come across two components I could use as switches - an NPN transistor or a solid state relay. Problem is, most of these seem to only be for low voltage applications. And in the case of NPN, I can't find one that has acceptable emitter-base and collector-base voltage limits. Can you recommend or point me to a source for components that might work for this project?
