Q4010N4RP

Triacs Overview

The Littelfuse Q4010N4RP is a bidirectional triac designed for surface-mount applications. It features an RMS on-state current of 10 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 50 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 25 mA to 50 mA. Non-repetitive peak on-state currents are specified at 100 A and 120 A, with an on-state voltage of 1.6 V.

Triacs Feature Summary

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

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuitry

Triacs Procurement Notes

Verify the specific suffix 'N4' against official Littelfuse documentation to confirm exact gate trigger current specifications, as variations exist within the Q4010 series. Ensure the ordering part number matches the required package type and tape/reel configuration for your manufacturing process. Cross-reference datasheet revisions to confirm compliance with current RoHS and REACH standards before finalizing procurement.

Triacs Selection Notes

Select this component when a 10 A RMS current rating and 400 V blocking voltage are required in a compact surface-mount form factor. Compare gate sensitivity requirements against the 2.5 V trigger voltage specification. Evaluate thermal management needs given the SMTO-263-2 package constraints and the +125°C maximum junction temperature limit for your specific application environment.

Triacs Part Context

This triac belongs to the Qxx10xx series from Littelfuse, which provides standardized high-current solutions for industrial and consumer electronics. The Q4010N4RP variant specifically targets applications requiring robust AC switching in space-constrained designs. It complements other devices in the family that offer different current ratings or voltage thresholds while maintaining consistent packaging and mounting characteristics.

Triacs Replacement Considerations

Direct replacements must match the 10 A RMS current, 400 V voltage rating, and SMTO-263-2 package. Verify equivalent gate trigger characteristics to ensure compatibility with existing drive circuits. Consult manufacturer substitution guides for confirmed cross-references.
