K2500GH Littelfuse

Teccor brand Thyristors High Energy Bidirectional SIDACs RoHS Kxxx0yH Series Description The new Kxxx0yH is a higher energy SIDAC switch for gas ignition applications requiring higher current pulse current especially at low repetition rate. It is offered in a DO-15 and TO-92 leaded packages as well as DO-214 surface mount package. Voltage activation of this solid state switch is accomplished with peak volt age level of 190 to 280Volts. The SIDAC is a silicon bilateral voltage triggered Thyristor switch that switches on through a negative resistance region to a low on-state voltage. Conduction will continue until current is interrupted or lowered below minimum holding current of the device. Features AC Circuit Oriented 280A Pulse Current Schematic Symbol Capability T riggering Volt age of 190 to 280V RoHS Compliant Applications Suitable for high voltage power supplies, natural gas igniters, and Xenon fl ash ignition.
