Kxxx0yH Series

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.
