K2400GHU

DIACs, SIDACs Overview

The Littelfuse K2400GHU is a high-energy unidirectional SIDAC switch designed for gas ignition applications requiring high pulse current at low repetition rates. It operates within a triggering voltage range of 230 V to 250 V and supports a repetitive peak off-state voltage of 210 V. The device features a maximum on-state RMS current of 1 A and can handle a peak repetitive pulse current of up to 280 A at 5 Hz. Packaged in a DO-15 leaded format, it includes a holding current maximum of 60 mA and an on-state voltage of 1.5 V at 1 A.

DIACs, SIDACs Feature Summary

• Unidirectional silicon bilateral voltage-triggered thyristor switch
• High surge current capability with 280 A pulse rating
• Glass-passivated junctions for AC circuit orientation

DIACs, SIDACs Applications

• Natural gas igniters
• Xenon flash ignition systems
• High voltage power supplies

DIACs, SIDACs Procurement Notes

Verify the specific package type and marking requirements against the design schematic before ordering. Confirm that the DO-15 bulk or reel packaging options align with the assembly line capabilities. Ensure the thermal resistance characteristics are compatible with the intended heat dissipation strategy for the target application environment.

DIACs, SIDACs Selection Notes

Select this component when a unidirectional high-energy trigger is required for gas ignition circuits. The K2400GHU variant specifically provides a 230 V to 250 V breakover voltage range. Consider the DO-15 through-hole package for robust mechanical mounting compared to surface mount alternatives like the SHU series.

DIACs, SIDACs Part Context

This part belongs to the K2xx0yHU series of high-energy unidirectional SIDACs from Littelfuse. The 'G' suffix denotes the DO-15 leaded package, while '240' indicates the specific 230 V to 250 V switching voltage range within the product family.

DIACs, SIDACs Replacement Considerations

The K2400SHU serves as the surface mount equivalent within the same electrical specification family. Other unidirectional SIDACs may require verification of breakover voltage tolerance and peak current handling capabilities to ensure functional compatibility.
