10kv 25mA switching?

[tearoffear]

I have to switch 10kv 25mA but I didn't find any component that fit my requirements. Are there any optoisolator ,triac,tristor or anything to do that.

Is it April 1 already?

what are your trying to do? maybe there is a better way so you dont have to switch such a problematic voltage.

You can stack HV mosfets to get up to 10kV blocking but their drive will be complicated with opto's. Is it AC or DC?

An spark gap shod do.

You can use a high voltage relay. Kilovac makes very good ones, http://relays.tycoelectronics.com/kilovac/

I have used them ( K43 series ) on an automated Hi-Pot tester for an industrial lamp ballast tester, switching 5 and 10 KV , very low current. The contacts are in a vacuum, very reliable.

I mounted them on an alluminum panel, the high voltage was on one side, the coil connections are on the other side.

Not cheap, but they do the job.

I will control Ac voltage. thanks for your interest.

from where? the mains? or a stepup trasformer
