K1800GURP

Overview

The Littelfuse K1800GURP is a high-voltage trigger diode (SIDAC) manufactured by Littelfuse, designed for surface mounting in the DO-214 package. It features a breakover voltage of 183 V and a maximum holding current of 80 mA. The device supports an RMS on-state current of 1 A with a non-repetitive peak current capability of 20 A. Rated for operation between -40°C and +125°C, it provides reliable overvoltage protection with low leakage characteristics.

Feature Summary

High-voltage triggering capability for circuit protection
Surface-mount design for automated PCB assembly
Robust surge handling with defined non-repetitive peak current rating

Applications

Overvoltage protection in telecommunications equipment
Surge suppression in industrial control systems
Triggering circuits for thyristors and triacs

Procurement Notes

Verify the exact part number against official Littelfuse documentation to ensure compatibility with the specific application requirements. Confirm that the DO-214 package and electrical parameters match the design specifications before procurement. Check for any recent updates to the datasheet regarding environmental compliance or manufacturing changes.

Selection Notes

Select this component based on its 183 V breakover voltage and 1 A RMS current rating. Ensure the operating temperature range of -40°C to +125°C meets the environmental conditions. Verify that the DO-214 package size fits the available PCB space and that the holding current of 80 mA is compatible with the latch-up requirements of the protected circuit.

Part Context

This SIDAC belongs to Littelfuse's high-voltage trigger diode family, offering bidirectional switching characteristics. It is distinct from standard TVS diodes by its latching behavior until current drops below the holding threshold. The DO-214 package provides a compact solution for surface-mount applications requiring robust transient protection.

Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic replacements may differ in breakover voltage tolerance or holding current, potentially affecting circuit reliability.
