Just found a workable solution to switch 4000 volts and 2000 amps. Time to go old-school!!!
Except there are three problems. The tube has no trigger electrode, only free running is possible. Each tube costs over $200. Also, each tube is filled with 5.44 MBq of radioactive tritium ☢️ ! #electronics

1. The high current discharge tube GXH series double electrode spark gap is a gas discharge tube, sealed in a glass/metal casing. It can provide tubes with a DC breakdown voltage ranging from 0.50KV to 5kV. This is represented by the number or number following the letter and is expressed in hundreds of volts.
