Fast HV Transistor Switches, HTS 30 - HTS 50 - HTS 80


  • 3kV or 5kV or 8kV
  • Galvanic Isolation
  • Fast Switching
  • High Repetition Rates

Typical applications

  • Acceleration Grid Drivers
  • Deflection Grid Drivers
  • Pockels Cell Drivers
  • HV Pulse Generators

These switches are designed for high voltage, high speed switching applications such as acceleration- and deflection grid drivers, pockels cell drivers and nano¬second pulse generators.
In contrast to conventional high voltage switches with cold cathode tubes, the transistor switches of model series HTS have a very short recovery time, so that multiple pulses of microseconds time separation or repetition rates up to 50.000 pulses per second are achievable. HTS transistor switches are practically jitter¬-free, highly reliable and have the live times typical for semiconductor devices. Neither trigger transformer nor high auxiliary voltages are required for operation. The switches are triggered by a positive going TTL pulse. In the standard version, the on-time after being triggered is typically 120 nanoseconds. Devices with on-¬times of up to 100 microseconds are optionally available. The turn-on rise time depends essentially on the operating voltage and the parasitic circuit capacitance, respectively load capacitance. Rise times of less than 5 nanoseconds are attainable with optimized circuit designs. Because of the galvanic isolation (more than 10.000 VDC), positive as well as negative voltages can be switched on or off, the switches can be floated also at a high potential.
