K2xx0yHU Series
Teccor® brand Thyristors
High Energy Unidirectional SIDACs
RoHS
Schematic Symbol

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.
Features
• A C circuit oriented
• T riggering Voltage of 190
to 260V
• 280A Pulse current
capability
• RoHS compliant
• Unidirectional
Applications
Suitable for high voltage power supplies, natural gas
igniters, and Xenon flash ignition.
