Teccor brand Thyristors Multipulse SIDACs RoHS Kxxx1G 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 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 (t ) makes this robust product best COMM suited for producing multiple pulses in each half cycle of 50/60 Hz line volt age. The Multipulse SIDAC is offered in DO-15 axial leaded package. Kxxx1G SIDAC has a repetitive off-st ate blocking volt age (V ) of 180V to 270V minimum depending actual device DRM type. Blocking capability is ensured by glass passivated Schematic Symbol junctions for best reliability. Package is epoxy encapsulation with tin-plated copper alloy leads. Features AC circuit oriented RoHS Compliant T riggering Volt age of 20 0 to 380V Applications Typical application circuit presented in Figure 10 of this dat a sheet (Typical Met al Halide Ignitor Circuit).
