K2400GURP

Overview

The Littelfuse K2400GURP is a high-voltage trigger diode, classified as a SIDAC within the thyristor subcategory. It operates in the DO-214AC (SMB) surface-mount package and supports SMD/SMT installation styles. The device features a breakover voltage (VBO) range of 220 V to 250 V and a rated repetitive off-state voltage (VDRM) of 190 V. It handles an on-state RMS current (It RMS) of 1 A and a non-repetitive on-state current of up to 20 A. The component maintains a maximum holding current of 150 mA and exhibits an on-state voltage of 1.5 V. It functions reliably across a temperature range from -40 °C to +85 °C.

Feature Summary

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

Applications

• Surge protection for sensitive electronic circuits
• Triggering elements for silicon-controlled rectifiers (SCRs)
• Overvoltage protection in AC power line applications

Procurement Notes

Verify the specific suffix 'URP' against official Littelfuse documentation to confirm reel packaging specifications and RoHS compliance status. Ensure the selected variant matches the required DO-214AC footprint and electrical ratings for your design. Cross-reference datasheet revisions to confirm parameter stability before finalizing procurement orders.

Selection Notes

Select this component when a bidirectional trigger device is required for overvoltage protection in surface-mount designs. Compare the 190 V VDRM and 220-250 V VBO parameters against system voltage requirements. Ensure the 1 A RMS current rating exceeds the expected load conditions. Verify that the DO-214AC package dimensions fit the available PCB real estate.

Part Context

This part belongs to the Littelfuse K-series SIDAC family, designed for high-voltage triggering applications. These devices are commonly used in conjunction with other thyristors or triacs to provide precise turn-on characteristics. The series offers various voltage ratings and package options to suit different circuit protection needs.

Replacement Considerations

Check Littelfuse substitution guides for equivalent SIDACs in the DO-214AC package. Verify that alternative parts match the 220-250 V breakover voltage and 1 A RMS current ratings. Ensure compatibility with existing PCB footprints and thermal management requirements.
