K2500S1URP

Overview

The Littelfuse K2500S1URP is a high-voltage trigger diode, classified as a SIDAC within the Teccor product family. It operates in the DO-214AC (SMA) surface-mount package with two leads. Key electrical parameters include a breakover voltage (VBO) of 260 V and a rated repetitive off-state voltage (VDRM) of 230 V. The device supports an RMS current rating of 1 A and can handle non-repetitive on-state currents of 16.7 A or 20 A. It features a maximum holding current of 80 mA and an on-state voltage of 1.2 V. The component functions reliably across a temperature range from -40°C to +150°C.

Feature Summary

• Bidirectional switching capability for AC circuit protection applications
• High surge current handling capacity for transient suppression
• Compact surface-mount design for automated assembly

Applications

• Surge protection for telecommunication lines
• Triggering devices for thyristors and triacs
• Overvoltage protection in industrial control systems

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before integration. Confirm that the DO-214AC footprint matches the target PCB layout. Ensure supply chain sources are authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when a precise 260 V breakover threshold is required for bidirectional triggering. Compare the 1 A RMS rating against circuit load requirements. Consider the 150°C maximum operating temperature for high-thermal environments. Evaluate the DO-214AC package size constraints relative to available board space.

Part Context

This part belongs to the Kxxx0yU series of SIDACs manufactured by Littelfuse under the Teccor brand. It shares the DO-214AC package form factor with other variants in the lineup but differs in breakover voltage ratings. The series is designed for robust overvoltage protection in compact electronic assemblies.

Replacement Considerations

Direct substitutes may include other Littelfuse SIDACs in the DO-214AC package with similar 260 V breakover voltages, such as the K2600S1URP if available. Verify pinout compatibility and thermal characteristics before substitution.
