Multipulse™ SIDACs
Kxxx1G Series
Kxxx1G Series
Description
The Multipulse™ SIDAC is a voltage switch used in Metal-
Halide lamp ignition circuits as well as High Pressure
Sodium lamp ignition circuits for outdoor street and area
lighting. This robust solid state switch is designed to handle
lamp igniter applications requiring operation at ambient
temperatures up to 90°C where igniter circuit components
can raise SIDAC junction temperature up to 125°C, especially
when the lamp element is removed or ruptured. Its excellent
commutation time (tCOMM) makes this robust product best
suited for producing multiple pulses in each half cycle of
50/60 Hz line voltage. The Multipulse™ SIDAC is offered in
DO-15 axial leaded package.
Kxxx1G SIDAC has a repetitive off-state blocking voltage
(VDRM) of 180V to 270V minimum depending actual device
type. Blocking capability is ensured by glass passivated
junctions for best reliability. Package is epoxy encapsulation
with tin-plated copper alloy leads.

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.
