K2400GRP

Overview

The Littelfuse K2400GRP is a high-voltage trigger diode (SIDAC) from the Kxxxzy series, designed for through-hole mounting in DO-15 packages. It features a breakover voltage range of 220 V to 250 V and a maximum breakover current of 10 uA. The device supports an RMS on-state current of 1 A and non-repetitive peak currents of 16.7 A or 20 A. Rated for a repetitive off-state voltage of 190 V with leakage current under 5 uA, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides precise high-voltage triggering via controlled breakover characteristics
• Capable of handling significant non-repetitive surge currents for ignition applications
• Designed for robust through-hole integration in compact assemblies

Applications

• High voltage power supplies
• Natural gas igniters
• High-pressure Sodium lamps
• Xenon flash ignition systems

Procurement Notes

Verify that the specific order corresponds to the K2400GRP variant, which utilizes the DO-15 through-hole package. Confirm that the required breakover voltage tolerance aligns with the 220 V to 250 V specification range. Ensure the application circuit can accommodate the 1 A RMS current rating and the specified thermal operating limits between -40°C and +85°C. Cross-reference the manufacturer's datasheet for any updates to the Kxxxzy series packaging or compliance standards before finalizing procurement.

Selection Notes

Select the K2400GRP when a through-hole component is required for high-voltage triggering circuits. This model is appropriate for designs needing a breakover voltage up to 250 V and an RMS current capacity of 1 A. It serves as a direct alternative to surface mount variants like the K2400SRP when PCB layout constraints favor axial leaded components. Ensure the system design accounts for the 190 V repetitive off-state voltage limit to prevent premature triggering during normal operation.

Part Context

The K2400GRP belongs to Littelfuse’s Kxxxzy SIDAC family, specialized for high-voltage switching and triggering. These devices function similarly to DIACs but offer higher voltage and current capabilities, making them suitable for industrial and consumer electronics requiring reliable ignition pulses. The DO-15 package provides mechanical stability for through-hole assembly processes commonly used in power supply and lighting control manufacturing.

Replacement Considerations

The K2400G is a verified through-hole substitute within the same series, offering identical electrical specifications and DO-15 packaging. Designers should verify that the replacement part meets the specific breakover voltage requirements of the target application.
