K2300GURP

Overview

The Littelfuse K2300GURP is a high-voltage trigger diode, classified as a SIDAC within the Teccor product family. Manufactured by Littelfuse, this component utilizes a DO-214AC (SMB) surface-mount package with two leads. It is designed for applications requiring precise voltage triggering and overvoltage protection. The device operates within a temperature range of -40°C to +150°C and features a rated repetitive off-state voltage of 200 V. Key electrical characteristics include a breakover voltage of 240 V, a maximum breakover current of 10 µA, and an on-state RMS current rating of 1 A.

Feature Summary

• High-voltage bidirectional switching capability for circuit protection
• Surface-mount construction compatible with automated assembly processes
• Robust thermal performance suitable for elevated operating environments

Applications

• Overvoltage protection in AC power supply circuits
• Triggering mechanisms for thyristors and triacs
• Surge suppression in industrial control systems

Procurement Notes

Verify the specific suffix 'G' against official Littelfuse documentation to confirm material composition or compliance variations compared to standard variants. Ensure the DO-214AC footprint matches the target PCB design. Confirm RoHS and REACH status through the manufacturer's certified datasheet before integration into regulated products.

Selection Notes

Select this component when a symmetric breakdown voltage near 240 V is required for triggering or protection. Compare the 1 A RMS current rating against peak load requirements. Ensure the DO-214AC package size fits the spatial constraints. Verify that the 80 mA holding current does not interfere with normal circuit operation during standby states.

Part Context

This part belongs to the Kxxx0yU series of SIDACs from Littelfuse's Teccor brand. These devices are silicon avalanche diodes designed for high-voltage switching. The K2300GURP shares functional similarities with other members of the K2300 series but may differ in specific manufacturing tolerances or packaging details defined by the manufacturer.

Replacement Considerations

Consult Littelfuse cross-reference guides for direct equivalents. Generic replacements must match the 240 V breakover voltage, 1 A RMS current, and DO-214AC package dimensions. Verify that substitute components meet the same thermal and electrical specifications.
