K2500SHU Datasheet | Littelfuse

escription The new K2xx0y HU 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 acplished with peak voltage 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 - T riggering Voltage of 190 to 260V - 280A Pulse current capability - Ro HS pliant - Unidirectional Applications Suitable for high voltage power supplies, natural gas igniters, and Xenon flash ignition.
