Q4016NH6RP

Triacs Overview

The Littelfuse Q4016NH6RP is a bidirectional triac from the Qxx16xHx series, designed for surface-mount applications in the SMTO-263-2 package. It features an RMS on-state current of 16 A and a rated repetitive off-state voltage (VDRM) of 400 V. The device exhibits a maximum on-state voltage of 1.6 V and a holding current (Ih) of up to 70 mA. Gate triggering requires a voltage (Vgt) of 2.5 V and a current (Igt) of 80 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A. Leakage current is limited to 50 uA at VDRM. Operating temperatures range from -40 C to +125 C.

Triacs Feature Summary

• Surface-mount construction in an isolated SMTO-263-2 package for automated assembly
• High noise immunity characteristics suitable for sensitive AC control circuits
• Glass-passivated junctions for long-term parameter stability and reliability

Triacs Applications

• AC motor speed control systems
• Solid-state relay switching modules
• Lighting dimmer and modulation controls

Triacs Procurement Notes

Verify the specific suffix RP indicates reel packaging versus tube variants like TP. Confirm RoHS compliance status through official Littelfuse documentation before integration. Ensure the ordering quantity aligns with factory minimum order requirements. Validate that the SMTO-263-2 footprint matches the target PCB design constraints.

Triacs Selection Notes

Select this component when a 400 V rating is sufficient for the AC line voltage. Compare against the Q8016NH6RP if higher voltage blocking is required. Consider thermal management needs given the 16 A RMS capability in a small SMD package. Verify gate drive compatibility with the 80 mA trigger current specification.

Triacs Part Context

This part belongs to the Qxx16xHx family of high-sensitivity triacs manufactured by Littelfuse. It shares core electrical parameters with other variants in the series, differing primarily in voltage ratings and packaging formats. The H designation typically denotes high sensitivity or specific gate characteristics within the product line.

Triacs Replacement Considerations

Direct substitutes include the Q4016NH6TP, which shares identical electrical specifications but utilizes tube packaging instead of reel format. Other family members like Q8016NH6RP offer higher voltage ratings but may require circuit adjustments.
