K2500F1

Overview

The Littelfuse K2500F1 is a high-voltage trigger diode, classified as a SIDAC, designed for robust circuit protection. It operates within a breakover voltage range of 240 V to 280 V and supports a maximum holding current of 150 mA. The device features a low on-state voltage of approximately 1.5 V and handles non-repetitive peak currents up to 20 A. Rated for a continuous RMS current of 1 A, it utilizes a DO-15 through-hole package. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

High-energy discharge capability for effective transient suppression
Bidirectional switching characteristic for AC circuit applications
Robust construction in a standard axial leaded package

Applications

Gas discharge tube triggering circuits
Overvoltage protection modules
Lightning surge arrestor drivers

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides original manufacturer certification to guarantee component authenticity and traceability for critical safety applications.

Selection Notes

Select this component when designing circuits requiring precise high-voltage triggering thresholds for protective devices. Consider the DO-15 package constraints for PCB layout and ensure the thermal management strategy accommodates the specified operating temperature range during fault conditions.

Part Context

This part belongs to the K-series SIDAC family from Littelfuse, engineered specifically for triggering gas discharge tubes and protecting sensitive electronics from high-energy transients. It serves as a reliable interface between control logic and high-power surge protection elements.

Replacement Considerations

Cross-reference with other SIDACs offering similar 240V-280V breakover voltages and DO-15 packages. Verify that substitute components match the 1A RMS current rating and 20A peak pulse handling capabilities to maintain circuit integrity.
