K2xx0yHU Series
Teccor® brand Thyristors
High Energy Unidirectional SIDACs
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.

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.
