Q4016NH4TP

Triacs Overview

The Littelfuse Q4016NH4TP is a bidirectional triac in the Qxx16xHx series, housed in an SMTO-263-2 surface-mount package. It supports an RMS on-state current of 16 A with a rated repetitive off-state voltage of 400 V. The device features a maximum on-state voltage of 1.6 V and a gate trigger current of 35 mA. It operates within a temperature range of -40°C to +125°C and maintains a low leakage current of 5 µA at VDRM.

Triacs Feature Summary

• Bidirectional AC switching capability for phase control applications
• Glass-passivated junctions for parameter stability and reliability
• Surface-mount construction compatible with automated assembly

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout and electrical tolerances. Ensure the procurement channel provides valid traceability documentation. Confirm that the component meets RoHS compliance requirements for the intended market. Validate the package type matches the PCB footprint design before finalizing orders.

Triacs Selection Notes

Select this component when a 16 A RMS current rating and 400 V blocking voltage are required in a compact surface-mount form factor. The high gate trigger current of 35 mA necessitates a driver capable of supplying sufficient gate power. Verify thermal management capabilities for the SMTO-263-2 package under continuous load conditions.

Triacs Part Context

This part belongs to the Teccor Qxx16xHx family of triacs manufactured by Littelfuse. These devices are designed for general-purpose AC switching where robust performance and noise immunity are critical. The series utilizes glass-passivated junction technology to ensure long-term reliability across varying environmental conditions.

Triacs Replacement Considerations

Cross-reference with other 16 A, 400 V triacs in the SMTO-263-2 package. Verify compatibility of gate trigger characteristics and holding current specifications with existing circuit designs before substitution.
