Teccor brand Thyristors Standard Bidirectional SIDACs RoHS Kxxx1GL 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 voltage. The Multipulse SIDAC is offered in a DO-15 axial leaded package. Kxxx1GL SIDAC has a repetitive off-state blocking voltage (V ) of 180V to 270V minimum depending actual device DRM type. Blocking capability is ensured by glass passivated Schematic Symbol junctions for best reliability. The package is epoxy encapsulated with tin plated copper alloy leads. Features AC circuit oriented RoHS Compliant T riggering Voltage of 200 Applications to 380V Typical application circuit presented in Figure 10 of this data sheet (Typical Metal Halide Ignitor Circuit).
