K2400F23RP

Overview

The K2400F23RP is a SIDAC device manufactured by Littelfuse Inc., designed for high-voltage circuit protection and triggering applications. It operates within a breakover voltage range of 79 V to 330 V, with specific variants such as the 220-250V model supporting peak currents up to 1 A. The component is housed in a TO-92 (TO-202) package, providing a compact form factor suitable for surface mounting or through-hole integration. This bidirectional trigger diode functions similarly to a DIAC but offers higher current handling capabilities, making it effective for phase control and ignition circuits where reliable high-voltage switching is required.

Feature Summary

• Bidirectional triggering capability for AC phase control applications
• High peak current handling capacity suitable for ignition systems
• Compact TO-92 package design for space-constrained layouts

Applications

• Natural gas igniters
• High-pressure sodium lamp ballasts
• Xenon flash ignition circuits
• High voltage power supply triggering

Procurement Notes

Verify the exact breakover voltage rating against the specific application requirements, as the K2400 series encompasses a wide range from 79 V to 330 V. Confirm that the TO-92 package type matches the PCB footprint constraints. Ensure the selected variant supports the necessary peak current for the intended load, typically up to 1 A for standard models. Cross-reference the datasheet specifications with the system's operating temperature range to guarantee reliability under thermal stress conditions.

Selection Notes

Select this component when designing circuits requiring reliable high-voltage triggering with moderate current demands. The choice depends on matching the specific breakover voltage to the desired firing point of the load, such as a thyristor or triac. Consider the thermal management capabilities of the TO-92 package if continuous operation near maximum ratings is expected. Evaluate the need for bidirectional symmetry if used in AC phase control scenarios versus unidirectional alternatives.

Part Context
