Kxxx0yH Series
High Energy Bidirectional SIDACs
High Energy 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.
