I am building a HV experimental setup for energy harvesting, where I have some HV capacitors in series. I need to put diodes between the caps to act as switches. The maximum reverse voltage they need to withstand is about 5kV. They need to have as low forward voltage as possible. Their switching speed is not too important.
Anyone got suggestions on what diodes to use?
