K2000SHRP

DIACs, SIDACs Overview

The Littelfuse K2000SHRP is a high-voltage trigger diode, classified as a SIDAC device within the K2xx0yHU series. It features a uni-directional configuration in a DO-214 surface-mount package. Key electrical parameters include a breakover voltage (VBO) of 230 V and a maximum breakover current (IBO) of 500 uA. The rated repetitive off-state voltage (VDRM) is 190 V, with a holding current (Ih) maximum of 60 mA. In the on-state, it exhibits a voltage drop of 1.5 V and supports an RMS current (It RMS) of 1 A. The component operates within a temperature range of -40 C to +125 C.

DIACs, SIDACs Procurement Notes

Verify the specific suffix 'P' against official Littelfuse documentation to confirm tape-and-reel packaging specifications. Ensure the ordering quantity aligns with standard reel quantities to avoid partial reel handling issues. Cross-reference the RoHS compliance status directly with the manufacturer's latest declaration before finalizing procurement orders.

DIACs, SIDACs Selection Notes

Select this component when a uni-directional trigger mechanism is required rather than bidirectional alternatives like the K2000 series. Confirm that the 230 V breakover voltage matches the target circuit's threshold requirements. Verify that the DO-214 package footprint fits the available PCB real estate and that the 1 A RMS current rating exceeds the expected load conditions.

DIACs, SIDACs Part Context

This part belongs to the K2xx0yHU family of high-voltage trigger diodes manufactured by Littelfuse. These devices are designed specifically for applications requiring precise voltage triggering thresholds. The K2000SHRP variant distinguishes itself through its uni-directional characteristic and surface-mount form factor, differentiating it from through-hole or bidirectional counterparts in the broader product lineup.

DIACs, SIDACs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic replacements may not match the specific 230 V breakover tolerance or the uni-directional behavior required for proper circuit operation.
