K1400GURP

Overview

The Littelfuse K1400GURP is a silicon unilateral voltage-triggered switch (SIDAC) designed for high-voltage protection applications. It features a breakover voltage range of 130 V to 146 V with a maximum breakover current of 10 uA. The device supports an RMS on-state current of 1 A and a non-repetitive peak pulse current of 12 A. Rated for a maximum repetitive off-state voltage of 90 V, it operates within a temperature range of -40°C to +85°C. Packaged in a DO-15 through-hole case, it exhibits a holding current of 150 mA and an on-state voltage of 1.5 V.

Feature Summary

Unilateral voltage-triggered switching action for overvoltage protection
High surge capability with 12 A peak pulse current rating
Robust through-hole DO-15 package construction

Applications

Gas discharge tube triggering circuits
Surge protection devices
Overvoltage protection for sensitive electronics

Procurement Notes

Verify the specific suffix 'URP' against the manufacturer's official documentation to confirm packaging configuration and availability status. Ensure the component matches the required DO-15 through-hole mounting style and that the breakover voltage tolerance aligns with the circuit design specifications before finalizing procurement orders.

Selection Notes

Select this component when a unilateral trigger device is required for gas discharge tubes or similar protection schemes. The 130-146 V breakover range suits applications needing precise voltage thresholding. Consider the 1 A RMS current rating for continuous load handling and the 12 A pulse rating for transient energy absorption during surge events.

Part Context

The K1400GURP belongs to the Kxxx0yU series of SIDACs from Littelfuse. These devices are engineered as silicon unilateral switches that conduct current only after exceeding a specific breakover voltage. They serve as critical interface components between control circuits and high-energy protective elements like gas tubes.

Replacement Considerations

Consult Littelfuse official substitution guides for compatible SIDACs within the K-series family. Verify equivalent breakover voltage ranges and current ratings to ensure functional compatibility without modifying the existing PCB layout or thermal management requirements.
