Kxxx1G Series

Multipulse™ SIDACs

Kxxx1G 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.

Kxxx1G SIDAC has a repetitive off-state blocking voltage

(V

type. Blocking capability is ensured by glass passivated

junctions for best reliability. Package is epoxy encapsulation

with tin-plated copper alloy leads.
