Q4010NH5RP

Triacs Overview

The Littelfuse Q4010NH5RP is an Alternistor TRIAC rated for 400V repetitive off-state voltage and 10A RMS on-state current. It operates within a temperature range of -40°C to +125°C and features a maximum holding current of 50mA. The device exhibits a typical on-state voltage of 1.6V, with gate trigger specifications of 1.3V and 50mA. Non-repetitive peak currents are specified at 110A and 120A under different conditions. Leakage current remains at 10uA at rated voltage. Packaged in an SMTO-263-2 surface mount format, it supports Reel, Cut Tape, and MouseReel packaging options.

Triacs Feature Summary

• Alternistor technology eliminates the need for external snubber networks
• Integrated diac trigger mechanism simplifies circuit design
• High noise immunity suitable for AC switching applications

Triacs Applications

• Lighting controls requiring high noise immunity
• Temperature modulation controls
• Speed control circuits for AC motors

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or Mouser Electronics. Confirm RoHS compliance status via official datasheets. Ensure ordering suffixes match required packaging formats such as Reel or Cut Tape. Validate part numbers against manufacturer catalogs to avoid counterfeits.

Triacs Selection Notes

Select this component for AC phase control where integrated triggering reduces bill of materials. The Alternistor architecture removes snubber requirements, saving space and cost. Verify thermal management capabilities for the SMTO-263-2 package in high-temperature environments up to 125°C.

Triacs Part Context

This device belongs to the Qxx12xHx series family from Littelfuse's Teccor brand. It shares functional similarities with other Quadrac devices that integrate triacs and diacs. The Q4010 variant specifically offers 10A current capacity compared to higher current models in the same series.

Triacs Replacement Considerations

Q4012NH5RP serves as a direct substitute with identical packaging but higher current rating. Q4010LH553 offers similar electrical characteristics in a TO-220AB through-hole package.
