K1100S1URP

Overview

The Littelfuse K1100S1URP is a high-voltage trigger diode (SIDAC) from the Kxxx0yU series, designed for surface-mount applications in the DO-214AC package. It features a nominal breakover voltage of 110 V with a maximum holding current of 80 mA and an RMS on-state current rating of 1 A. The device supports non-repetitive peak currents up to 20 A and operates within a temperature range of -40°C to +150°C.

Feature Summary

Provides bidirectional triggering capability for overvoltage protection circuits
Designed for surface-mount integration using standard SMD/SMT assembly processes
Engineered for high thermal stability with operation up to +150°C

Applications

Surge protection modules for telecommunications equipment
Overvoltage protection in AC mains sensing circuits
Triggering elements for thyristor-based crowbar circuits

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging configurations. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure the ordering quantity aligns with the standard reel packaging requirements specified in the product datasheet.

Selection Notes

Select this component when a 110 V breakover threshold is required for bidirectional surge suppression. Compare the 1 A RMS current rating against circuit load requirements. Verify that the DO-214AC footprint matches the PCB layout constraints. Consider the +150°C maximum operating temperature for high-thermal environments.

Part Context

This part belongs to the Littelfuse Teccor SIDAC family, specifically the K-series designed for surface-mount technology. It serves as a robust alternative to through-hole variants like the K1100G, offering similar electrical characteristics in a compact form factor suitable for automated assembly and space-constrained designs.

Replacement Considerations

The through-hole K1100G offers identical electrical ratings but requires different mounting infrastructure. Surface-mount alternatives within the same voltage class include the K1050S1URP and K2300S1URP, though their breakover voltages differ significantly.
