Standard Bidirectional SIDACs

Kxxx1GL Series

Description

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

suited for producing multiple pulses in each half cycle of

DO-15 axial leaded package.

Kxxx1GL SIDAC has a repetitive off-state blocking voltage

(V

type. Blocking capability is ensured by glass passivated

junctions for best reliability. The package is epoxy

encapsulated with tin plated copper alloy leads.
