Q4025N5RP

Triacs Overview

The Littelfuse Q4025N5RP is a bidirectional triac designed for surface-mount applications. It features an RMS on-state current of 25 A and a rated repetitive off-state voltage (VDRM) of 400 V. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-263-2 package. Key electrical parameters include a maximum holding current of 100 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 50 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A, with an on-state voltage of 1.8 V and an off-state leakage current of 10 uA.

Triacs Feature Summary

• Surface-mount construction in an SMTO-263-2 package for automated PCB assembly
• Bidirectional switching capability for AC power control circuits
• High thermal stability supporting operation up to +125°C junction temperature

Triacs Applications

• Solid-state relays requiring compact form factors
• AC motor speed control systems
• Lighting dimmer circuits

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified supply chain partners. Confirm RoHS compliance status via official documentation prior to integration. Ensure storage conditions maintain moisture sensitivity levels according to manufacturer guidelines for leaded surface-mount devices.

Triacs Selection Notes

Select this component when a 25 A RMS current rating and 400 V blocking voltage are required in a surface-mount topology. Verify that the 50 mA gate trigger current aligns with the driving circuit capabilities. Consider the SMTO-263-2 footprint constraints during PCB layout design.

Triacs Part Context

This part belongs to the Littelfuse Qxx25xx series of high-current triacs. It shares the 25 A current rating architecture with other variants in the family but is distinguished by its specific 400 V voltage class and surface-mount packaging configuration.

Triacs Replacement Considerations

Direct substitutes include Q4025NH6RP and QK025N5RP from the same manufacturer. Verify pinout compatibility and thermal resistance characteristics before substitution.
