Q4016NH6TP

Triacs Overview

The Littelfuse Q4016NH6TP is a bidirectional triac designed for surface mount applications. It features an RMS on-state current of 16 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. Key electrical parameters include a maximum holding current of 70 mA, a gate trigger current of 80 mA, and a gate trigger voltage of 2.5 V. It exhibits an on-state voltage of 1.6 V and a non-repetitive peak on-state current capability of 167 A or 200 A depending on the specific test condition. The component utilizes an SMTO-263-2 package.

Triacs Feature Summary

• Surface mount construction in an SMTO-263-2 package for automated assembly
• Bidirectional switching capability with high thermal stability up to 125°C
• Defined gate sensitivity with specified trigger voltage and current thresholds

Triacs Applications

• AC power control circuits
• Solid-state relay outputs
• Lighting dimmer modules

Triacs Procurement Notes

Verify the exact datasheet revision and RoHS compliance status directly with Littelfuse before finalizing design specifications. Confirm that the SMTO-263-2 footprint matches the target PCB layout requirements. Ensure that the 400V rating provides sufficient margin for the specific AC line voltage application being designed.

Triacs Selection Notes

Select this component when a 16A RMS current capacity and 400V blocking voltage are required in a surface mount form factor. Consider the 80mA gate trigger current requirement for driver circuit compatibility. Evaluate thermal management needs given the 125°C maximum junction temperature limit and the specific on-state voltage drop characteristics.

Triacs Part Context

This part belongs to the Qxx16xHx series of triacs from Littelfuse. The series is characterized by its robust construction suitable for industrial and consumer power control applications. The 'NH' suffix typically denotes specific thermal and electrical performance attributes within the manufacturer's product family.

Triacs Replacement Considerations

Consult official Littelfuse cross-reference documentation for verified equivalent parts. Do not substitute based solely on matching current and voltage ratings without verifying gate trigger characteristics and package pinout compatibility.
