Overview
K2xx0yHU Series Teccor® brand Thyristors High Energy Unidirectional SIDACs RoHS Schematic Symbol K A 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 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 • RoHS compliant • Unidirectional Applications Suitable for high voltage power supplies, natural gas igniters, and Xenon flash ignition.
