Description

The Multipulse™ SIDAC is a voltage switch used in Metal­Halide 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
suited for producing multiple pulses in each half cycle of
50/60 Hz line voltage. The Multipulse

) makes this robust product best

SIDAC is offered in a

DO-15 axial leaded package.

Kxxx1GL SIDAC has a repetitive off-state blocking voltage
(V

) 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.
