High Energy Bidirectional SIDACs

Kxxx0yH Series

Schematic Symbol

RoHS

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

• AC Circuit Oriented

• Triggering Voltage of 190

to 280V

• 280A Pulse Current

Capability

• RoHS Compliant

Applications

Suitable for high voltage power supplies, natural gas
igniters, and Xenon flash ignition.

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.
