K2400GHRP

Overview

The Littelfuse K2400GHRP is a high-voltage trigger diode, classified as a SIDAC within the thyristor subcategory. Manufactured by Littelfuse, this component utilizes a DO-15 through-hole package for circuit integration. It operates within a temperature range of -40°C to +85°C and carries an RMS current rating of 1 A. The device features a breakover voltage (VBO) between 220 V and 250 V, with a maximum breakover current (IBO) of 10 uA. In the closed state, it maintains a rated repetitive off-state voltage (VDRM) of 190 V and a leakage current of 5 uA. Upon triggering, the on-state voltage drops to 1.5 V, while the holding current (Ih) maximum is specified at 150 mA.

Feature Summary

• Bidirectional high-energy surge protection capability utilizing SIDAC technology
• Through-hole mounting configuration in a standard DO-15 axial leaded package
• Defined low on-state voltage characteristic for efficient energy dissipation during conduction

Applications

• Surge protection circuits for industrial equipment
• Overvoltage protection in AC power line interfaces
• Triggering applications for silicon controlled rectifiers (SCRs)

Procurement Notes

Verify the specific manufacturer part number against official Littelfuse documentation to confirm availability and exact specifications. Ensure that the DO-15 through-hole package aligns with the target PCB layout requirements. Confirm compliance with relevant RoHS and REACH standards prior to final procurement decisions.

Selection Notes

Select this component based on its 220 V to 250 V breakover voltage range and 1 A RMS current handling capacity. Ensure the operating environment remains within the -40°C to +85°C temperature limits. Verify that the DO-15 package dimensions fit the designated board space and that the 150 mA holding current meets the circuit's latching requirements.

Part Context

The K2400GHRP belongs to the Kxxxzy series of high-voltage trigger diodes produced by Littelfuse. This series is designed for robust overvoltage protection in various electronic systems. The component functions as a bidirectional switch, remaining non-conductive until the applied voltage exceeds the breakover threshold, at which point it conducts heavily to clamp the voltage.

Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic replacements may differ in breakover voltage tolerances or peak current ratings. Ensure any substitute component matches the DO-15 package and electrical characteristics precisely.
