High Energy Bidirectional SIDACs
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 voltage 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 Schematic Symbol to 280V Applications Suitable for high voltage power supplies, natural gas igniters, and Xenon flash ignition. Electrical Specifications (TJ = 25C, unless otherwise specified)

Design Considerations Careful selection of the correct device for the application's operating parameters and environment will go a long way toward extending the operating life of the Thyristor. Overheating and surge currents are the main killers of SIDACs. Correct mounting, soldering, and forming of the leads also help protect against component damage.
