K2200SHRP

Overview

The Littelfuse K2200SHRP is a high-voltage trigger diode (SIDAC) belonging to the K2xx0yHU series. It features a bidirectional switching characteristic in a DO-214 surface-mount package. Key electrical parameters include a breakover voltage (VBO) of 230 V, a maximum breakover current (IBO) of 500 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 with a holding current (Ih) maximum of 60 mA. It operates within a temperature range of -40 C to +125 C.

Feature Summary

• Bidirectional high-voltage triggering capability for symmetric circuit protection
• Surface-mount construction compatible with automated SMD/SMT assembly processes
• Robust thermal performance suitable for industrial operating environments

Applications

• Overvoltage protection for sensitive electronic circuits
• Triggering elements in thyristor-based control systems
• Surge suppression in AC power line interfaces

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with RoHS and REACH requirements for the target market. Confirm that the DO-214 footprint matches the design layout before finalizing procurement orders.

Selection Notes

Select this component when a bidirectional trigger mechanism is required for voltages around 230 V. Compare the 500 uA breakover current limit against alternative SIDACs if lower leakage or faster triggering is needed. Verify that the 1 A RMS current rating meets the peak load demands of the application circuit.

Part Context

This part belongs to the Littelfuse K2xx0yHU family of high-voltage trigger diodes. These devices are designed as alternatives to traditional gas discharge tubes, offering faster response times and more precise voltage thresholds. The series provides reliable protection for semiconductor components in harsh electrical environments.

Replacement Considerations

Consult Littelfuse cross-reference guides for verified substitutes. Ensure any replacement maintains the 230 V breakover voltage and DO-214 package dimensions to fit existing PCB footprints without redesign.
