K2200S1URP

Overview

The K2200S1URP is a high-voltage trigger diode (SIDAC) manufactured by Littelfuse under the Teccor brand. It operates in the DO-214AC-2 surface-mount package and belongs to the Kxxx0yU series. Key electrical parameters include a breakover voltage (VBO) of 230 V, a maximum breakover current (IBO) of 10 uA, and a rated repetitive off-state voltage (VDRM) of 190 V. The device supports an RMS on-state current (It RMS) of 1 A and non-repetitive on-state currents of 16.7 A or 20 A. It maintains a holding current (Ih) maximum of 80 mA and an on-state voltage of 1.2 V. The component functions within a temperature range of -40 C to +150 C.

Feature Summary

• Provides bidirectional high-voltage triggering for circuit protection applications
• Features low breakover current for sensitive gate drive isolation
• Designed for surface-mount integration with robust thermal stability

Applications

• Gas discharge tube (GDT) triggering circuits
• Lightning surge protection devices
• Overvoltage protection for thyristor gates

Procurement Notes

Verify the specific suffix URP against official Littelfuse documentation to confirm RoHS compliance and reel packaging details. Confirm that the DO-214AC-2 footprint matches the target PCB design. Ensure the 230 V breakover voltage aligns with the system's insulation requirements before finalizing procurement specifications.

Selection Notes

Select this component when a precise 230 V breakover threshold is required for GDT triggering. Compare the 10 uA IBO limit against alternative SIDACs if lower trigger currents are needed. Verify that the 1 A RMS current rating suffices for the expected surge energy levels in the intended application environment.

Part Context

This part belongs to the Littelfuse Teccor K-series SIDAC family, specifically designed for high-voltage switching. The K2200S1URP variant utilizes the DO-214AC-2 package, distinguishing it from through-hole versions like the K2200GURP. It serves as a critical interface between low-voltage control circuits and high-voltage surge arresters.

Replacement Considerations

The K2200SHURP offers similar triggering characteristics but features a different maximum operating temperature of +125 C compared to the +150 C rating of the K2200S1URP. Verify thermal management requirements when considering substitution.
