Fast HV Thyristor Switches, HTS 240-1000-SCR/DT – HTS 220-1000-SCR/DT


  • 24 kV or 22 kVDC @ 10 kA
  • Extremely High di/dt
  • High Surge Current Capability

Typical applications

  • Surge Generators
  • Crow Bar Circuits
  • Flash Lamp Drivers
  • Shock Wave Generators

These solid-state switches are designed for high voltage high peak current switching applications such as shock wave generators, flash lamp drivers, crow bar circuits and surge generators. The switching modules contain a large number of reverse blocking thyristors (SCR) with a special chip architecture for high surge conditions. Several hundred of these SCR's, each with its own low-impedance gate drive, are connected in series and in parallel to ensure the extreme di/dt of up to 16 kA/µs. The safe and synchronous control of all SCRs is performed by a patented driver which provides also the high galvanic isolation necessary for high-side circuits and safety-relevant applications.
