Fast HV Thyristor Switches, HTS 240-800-SCR – HTS 320-800-SCR


  • 24kVDC at 8kA or 32 kVDC at 8kA
  • 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.
