K2400EH70RP3

Overview

The Littelfuse K2400EH70RP3 is a high-voltage trigger diode (Sidac) designed for surge protection applications. It operates within a breakover voltage range of 220 V to 250 V and supports a maximum breakover current of 10 uA. The device features a rated repetitive off-state voltage of 190 V with a leakage current of 5 uA at this voltage. It handles non-repetitive on-state currents of 16.7 A or 20 A and maintains an RMS current rating of 1 A. The component utilizes a TO-92 package for through-hole mounting, ensuring reliable performance across an operating temperature range from -40 C to +85 C.

Feature Summary

• High-energy discharge capability for robust surge suppression
• Uni-directional switching behavior for precise triggering
• Through-hole construction for secure mechanical attachment

Applications

• Surge protection circuits in electronic equipment
• Triggering mechanisms for thyristor-based protection devices
• Overvoltage protection in industrial control systems

Procurement Notes

Verify the specific suffix RP3 against official Littelfuse documentation to confirm reel packaging specifications and quantity constraints. Ensure compatibility with existing board layouts for TO-92 through-hole mounting. Cross-reference electrical parameters such as breakover voltage tolerance and thermal limits with system requirements before finalizing procurement decisions.

Selection Notes

Select this component when uni-directional high-voltage triggering is required rather than bidirectional options like Diacs. Consider the TO-92 package size for through-hole assembly processes. Evaluate the 1 A RMS current rating against peak load demands. Confirm that the 220 V to 250 V breakover range aligns with the circuit's protection threshold needs.

Part Context

This part belongs to the Kxxxzy series of Sidacs manufactured by Littelfuse. These components are categorized under Thyristors and specifically designed for high-energy applications. The series offers various packaging options, with the RP3 suffix indicating tape and reel delivery for automated assembly processes.

Replacement Considerations

K2400EH70RP2 serves as a bulk alternative within the same series. Verify package type differences between reel and bulk configurations.
