K2400GAP

Overview

The Littelfuse K2400GAP is a high-voltage trigger diode (SIDAC) from the Kxxxzy series, designed for breakover and pulse-trigger applications. It features a bidirectional structure with a breakover voltage range of 220 V to 250 V at 10 µA. The device supports a maximum repetitive off-state voltage of 190 V and an RMS on-state current of 1 A. Non-repetitive peak currents reach up to 20 A. It operates within a temperature range of -40°C to +85°C and is housed in a DO-15 through-hole package.

Feature Summary

• Bidirectional high-voltage triggering capability for symmetrical circuit protection
• Predictable breakover voltage characteristics for reliable pulse generation
• Robust non-repetitive surge current handling for transient suppression

Applications

• High voltage power supply trigger circuits
• Natural gas igniter systems
• High-pressure sodium lamp ballasts
• Xenon flash ignition modules

Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with the required package style and electrical tolerances. Confirm that the component meets all relevant RoHS and REACH regulatory standards for the intended market. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a precise, symmetric breakover voltage is required for triggering thyristors or triacs in high-voltage environments. Ensure the application current does not exceed the 1 A RMS rating and that the operating temperature remains within the specified industrial limits. Consider the DO-15 package dimensions for PCB layout constraints.
