K2500SRP

Overview

The Littelfuse K2500SRP is a high-voltage trigger diode (SIDAC) belonging to the SRP series, designed for robust overvoltage protection in electronic circuits. It operates within a breakdown voltage range of 240 V to 280 V and features a maximum holding current of 150 mA. The device supports an RMS on-state current of 1 A and can withstand non-repetitive peak currents up to 20 A. Packaged in a DO-15 axial through-hole configuration, it functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

High-energy discharge capability for effective transient suppression
Bidirectional symmetrical switching characteristics
Robust construction suitable for demanding industrial environments

Applications

Gas discharge tube triggering circuits
Surge protection modules for telecommunications
Industrial control system input protection

Procurement Notes

Verify the specific suffix 'SRP' against official Littelfuse documentation to confirm package type and tape/reel specifications. Ensure compatibility with automated assembly processes if surface-mount or reel-based handling is required. Cross-reference RoHS compliance status directly with the manufacturer's latest declaration.

Selection Notes

Select this component when circuit design requires a precise breakdown voltage window between 240 V and 280 V. Evaluate thermal management requirements given the 1 A RMS rating. Confirm that the DO-15 package dimensions fit the available PCB real estate and mounting constraints.

Part Context

This part belongs to the Littelfuse SIDACtor family, specialized for triggering gas discharge tubes and providing secondary protection. The SRP variant typically denotes specific packaging or handling configurations compared to standard bulk versions.

Replacement Considerations

Direct substitutes include other SIDACs with similar 250V breakdown ratings such as the K2500GH, provided the package style matches the existing footprint. Verify holding current and peak pulse capabilities before substitution.
