Multipulse™ SIDACs
Kxxx1GL Series
Kxxx1GL 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 (t
COMM
) 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 a
DO-15 axial leaded package.
Kxxx1GL SIDAC has a repetitive off-state blocking voltage
(V
DRM
) of 180V to 200V minimum depending actual device
type. Blocking capability is ensured by glass passivated
junctions for best reliability. The package is epoxy
encapsulated with tin plated copper alloy leads.
