These switches are designed for high voltage, high current switching applications in which loads of very low impedances (e.g. large capacitances) must be driven with very short transition times. Compared to conventional high voltage switches using cold cathode tubes, thyratrons or spark gaps, the solid state switches of model series HTS have a very short recovery time, a high repetition rate, low jitter and a lifetime typical for semiconductor devices. Because of the TTL-compatible trigger input, HTS ¬switches require no complex drive circuitry and no high auxiliary voltages. The switches described in this data sheet have a fixed on-duration of 150 nanoseconds which can be extended optionally up to 100 microseconds. Due to the galvanic isolation of more than 10 KVDC, positive as well as negative voltages can be switched on or off, the switches can also be floated at a high potential.
