Schematic Symbol
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
• A C Circuit Oriented
• T riggering Voltage of 190
to 280V
• 2 80A Pulse Current
Capability
• RoHS Compliant
Applications
Suitable for high voltage power supplies, natural gas
igniters, and Xenon flash ignition.

1) Blocking capability may be lost during
and immediately following surge
current interval.
2) Overload may not be repeated until
junction temperature has returned
to steady-state rated value.
