K2201GLRP

Overview

The K2201GLRP is a bidirectional trigger diode (SIDAC) from Littelfuse's Teccor Multipulse series, designed for high-voltage switching applications. It operates in the DO-15 axial leaded package with through-hole mounting. Key electrical parameters include a breakover voltage (VBO) of 230 V and a maximum turn-on current (IBO) of 10 uA. The device supports a repetitive off-state blocking voltage (VDRM) of 200 V minimum and handles an RMS on-state current (It RMS) of 1 A. It features a non-repetitive peak on-state current capacity of 20 A and a holding current (Ih) maximum of 30 mA. The component functions within a temperature range of -40°C to +90°C.

Feature Summary

• Multipulse capability for generating multiple pulses per half-cycle of line voltage
• Robust solid-state design suitable for lamp igniter environments
• Bidirectional AC switching functionality

Applications

• Metal Halide lamp ignition circuits
• High Pressure Sodium lamp ignition circuits for outdoor street lighting
• Area lighting systems requiring robust voltage switching

Procurement Notes

Verify the specific suffix GLRP against official Littelfuse documentation to confirm the DO-15 package and Multipulse characteristics. Ensure compatibility with ambient operating temperatures up to 90°C and junction temperatures reaching 125°C during fault conditions such as lamp rupture. Confirm RoHS compliance status via the manufacturer's datasheet before integration.

Selection Notes

Select this component when designing ignition circuits for metal halide or high-pressure sodium lamps that require reliable multipulse generation. The DO-15 package suits through-hole PCB layouts. Verify that the 200 V VDRM and 230 V VBO align with the specific lamp ballast requirements. Consider the 1 A RMS current rating for circuit protection needs.

Part Context

The K2201GLRP belongs to the Teccor Multipulse SIDAC family, engineered specifically for demanding lighting applications. Unlike standard trigger devices, this series emphasizes commutation speed and durability in high-temperature environments typical of outdoor street lighting fixtures where components may face elevated thermal stress.

Replacement Considerations

Consult Littelfuse documentation for direct substitutes within the Kxxx1GL series. Verify pinout compatibility and electrical parameter equivalence, particularly VBO and VDRM values, before replacing existing components in production assemblies.
