HV switches current depending on-time, Thyristor / SCR

Unlike classical disc thyristor switches with very limited dv/dt and di/dt capabilities, the fast thyristor switching modules are made of a very large number of smaller thyristor dies (type depending up to 1000 single thyristors), connected in parallel and in series, so that the extreme dv/dt and di/dt is efficiently splitted to uncritical values for the the single thyristors. Every single thyristor is fired by its own highly synchronized and isolated gate driver. This makes a very short gate wiring possible and avoids dangerous hot spots known from classical thyristor switch designs



  • High peak current capability
  • Very overload tolerant
  • Easy firing by a simple TTL trigger pulse (2-5 V)
