Q2016NH3RP

Triacs Overview

The Littelfuse Q2016NH3RP is a bidirectional triac designed for AC power control applications. It belongs to the Qxx16xHx series and features an RMS on-state current of 16 A with a rated repetitive off-state voltage (VDRM) of 800 V. The device exhibits a typical on-state voltage of 1.6 V and a maximum holding current of 70 mA. Gate triggering requirements include a voltage of 2.5 V and a current of 80 mA. It operates within a temperature range of -40°C to +125°C and is housed in an SMTO-263-2 surface-mount package.

Triacs Feature Summary

• Bidirectional solid-state switching capability for AC circuits
• High thermal stability suitable for demanding industrial environments
• Surface-mount construction for automated PCB assembly

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Industrial heating element regulation

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or direct manufacturer channels. Confirm RoHS compliance status and specific reel packaging quantities prior to order placement. Ensure storage conditions align with semiconductor handling standards to maintain device integrity before soldering.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 16 A continuous current rating are required for AC load switching. Evaluate gate drive circuitry to ensure it can supply the specified 80 mA trigger current reliably. Consider thermal management strategies given the SMTO-263-2 package constraints for high-power dissipation scenarios.

Triacs Part Context

This part is a member of the Qxx16xHx family of high-performance triacs from Littelfuse. These devices are engineered for robust AC power control, offering improved dv/dt ratings and thermal performance compared to standard thyristors. The series supports various voltage ratings while maintaining consistent current handling capabilities.

Triacs Replacement Considerations

Direct replacements may include other 800 V, 16 A triacs in TO-263 packages from manufacturers such as STMicroelectronics or ON Semiconductor. Verify pinout compatibility and electrical parameter equivalence before substitution.
