Teccor brand Thyristors High Energy Unidirectional SIDACs RoHS K2xx0yHU Series Description The new K2xx0yHU 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 leaded package and DO-214AA surface mount package. Voltage activation of this solid state switch is accomplished with peak volt age level of 190 to 260Volts. 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 A C circuit oriented RoHS compliant Schematic Symbol T riggering Volt age of 190 Unidirectional to 260V 280A Pulse current capability A K Applications Suitable for high voltage power supplies, natural gas igniters, and Xenon fl ash ignition.
