The MultipulseTM 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 90C where igniter circuit components can raise SIDAC junction temperature up to 125C, 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 MultipulseTM SIDAC is offered in DO-15 axial leaded package.
