K2400SHRP

Overview

The Littelfuse K2400SHRP is a high-voltage trigger diode (SIDAC) belonging to the K2xx0yHU series. It features a bidirectional structure within a DO-214 surface-mount package. Key electrical parameters include a breakover voltage (VBO) of 250 V, a maximum breakover current (IBO) of 500 uA, and a rated repetitive off-state voltage (VDRM) of 210 V. The device supports an RMS on-state current (It RMS) of 1 A with an on-state voltage of 1.5 V. It operates reliably within a temperature range of -40 C to +125 C.

Feature Summary

• Bidirectional high-voltage triggering capability for symmetric circuit protection
• Surface-mount construction in a compact DO-214 package for automated assembly
• Designed for robust performance in harsh environments up to 125 C

Applications

• Overvoltage protection for sensitive electronic circuits
• Triggering elements for thyristor-based control systems
• Surge protection in industrial equipment

Procurement Notes

Verify the specific suffix 'RP' against official Littelfuse documentation to confirm tape-and-reel packaging configuration. Ensure compliance with RoHS and REACH requirements as specified in the manufacturer's datasheet before integration into final assemblies.

Selection Notes

Select this component when a bidirectional trigger mechanism is required for voltages around 240 V. The DO-214 package suits space-constrained PCB designs. Confirm that the 1 A RMS current rating meets the load requirements of the protected circuit.

Part Context

This part belongs to the K2xx0yHU family of SIDACs from Littelfuse. These devices are specialized semiconductor components designed for high-voltage switching applications, distinct from standard TVS diodes or fuses.

Replacement Considerations

Consult Littelfuse official substitution guides for compatible SIDACs with matching VBO and package dimensions. Verify pinout compatibility and thermal characteristics before replacing.
