K2500GHRP

DIACs, SIDACs Overview

The Littelfuse K2500GHRP is a high-energy silicon bilateral voltage-triggered switch (SIDAC) housed in a DO-15 axial through-hole package. It features a breakover voltage range of 240V to 280V and supports a peak output current of 1A. The device operates within a temperature range of -40°C to +125°C, with a hold current of 150mA and an off-state voltage of 200V.

DIACs, SIDACs Feature Summary

• Bilateral voltage-triggered switching capability for AC circuits
• High energy handling capacity suitable for surge protection applications
• Robust DO-15 axial leaded construction for reliable mounting

DIACs, SIDACs Applications

• Surge protection devices
• Triggering elements for thyristors and triacs
• Overvoltage protection circuits

DIACs, SIDACs Procurement Notes

Verify the specific suffix 'RP' indicates reel packaging versus bulk options like 'GH'. Confirm RoHS compliance status as some sources indicate non-compliance. Ensure the supplier provides valid datasheets matching the 240-280V breakover range. Check for shipping restrictions that may apply to this component in certain regions.

DIACs, SIDACs Selection Notes

Select this part when a bilateral trigger device with a 240-280V threshold is required. The 1A peak current rating suits moderate energy applications. The DO-15 package facilitates easy integration into through-hole designs. Consider thermal limits and hold current requirements for the specific circuit topology.

DIACs, SIDACs Part Context

This component belongs to the Kxxx0yH SIDAC series from Littelfuse. These devices are designed as silicon bilateral switches that conduct current once the applied voltage exceeds the breakover point. They serve as critical triggering components in protective circuits against transient overvoltages.

DIACs, SIDACs Replacement Considerations

The K2500GHAP is a documented alternative offering similar specifications in a different packaging format. Verify electrical parameters match exactly before substitution. Ensure the replacement maintains the required breakover voltage tolerance and peak current capabilities.
