Q2016NH6RP

Triacs Overview

The Littelfuse Q2016NH6RP is a bidirectional triac designed for high-power AC switching applications. It features an RMS on-state current (It RMS) of 16 A and a rated repetitive peak off-state voltage (VDRM) of 200 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Key electrical characteristics include a maximum holding current (Ih) of 70 mA, a gate trigger voltage (Vgt) of 2.5 V, and a gate trigger current (Igt) of 80 mA. The on-state voltage is specified at 1.6 V, with non-repetitive peak on-state currents rated at 167 A and 200 A.

Triacs Feature Summary

• High thermal stability supporting operation up to +125°C
• Surface-mount construction for automated assembly efficiency
• Robust surge handling capability for inductive loads

Triacs Applications

• Solid-state relay modules
• Industrial motor speed control circuits
• Lighting dimmer systems

Triacs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before finalizing design integration. Confirm that the SMTO-263-2 footprint matches the target PCB layout requirements. Ensure that the 200 V rating aligns with the system's peak line voltage specifications to prevent overvoltage failure during transient events.

Triacs Selection Notes

Select this component when a 16 A RMS current capacity is required alongside a 200 V blocking voltage. The SMTO-263-2 package offers a balance between thermal dissipation and board space constraints compared to larger through-hole alternatives. Consider the 70 mA holding current requirement to ensure reliable latching in low-load scenarios without premature turn-off.

Triacs Part Context

This part belongs to the Qxx16xHx series of high-current triacs from Littelfuse. The series is characterized by its robust silicon structure designed for demanding power control environments. Similar parts in the lineup vary primarily by voltage ratings, such as the Q4016 or Q8016 variants, while maintaining consistent current handling and packaging standards.

Triacs Replacement Considerations

Direct substitutes may include other 16 A, 200 V triacs in the SMTO-263-2 package from Littelfuse or competitors, provided pinout compatibility and thermal resistance values are verified against the original datasheet specifications.
