QV6016LH4TP

Triacs Overview

The Littelfuse QV6016LH4TP is a bidirectional triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 16 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package. Key electrical characteristics include a gate trigger current (Igt) of 35 mA, a holding current (Ih) maximum of 50 mA, and a non-repetitive peak on-state current capability of 167 A or 200 A depending on the specific test condition defined in the datasheet.

Triacs Feature Summary

• High thermal stability with a maximum operating junction temperature of +125°C
• Robust surge handling capability with high non-repetitive peak on-state current ratings
• Sensitive gate drive requirements with a specified gate trigger current of 35 mA

Triacs Applications

• AC motor speed control circuits
• Solid-state relay designs
• Lighting dimmer switches

Triacs Procurement Notes

Verify the exact datasheet revision and electrical parameter limits directly from the manufacturer before finalizing design specifications. Confirm that the TO-220-2 package isolation requirements match the system's thermal and electrical insulation needs. Ensure the gate drive circuit can reliably supply the minimum 35 mA trigger current under all operating conditions.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 16 A continuous current capacity are required in a standard through-hole form factor. Compare the 167 A versus 200 A non-repetitive current ratings against the specific application's surge profile to ensure adequate safety margins. Verify compatibility with the intended PCB layout for the TO-220-2 mounting style.

Triacs Part Context

This part belongs to the Qxx16xHx series of triacs from Littelfuse, which are engineered for general-purpose AC switching. The series provides a balance of high current density and reliable triggering characteristics suitable for industrial and consumer electronics. The 'Q' designation typically indicates specific silicon technology optimized for robustness in AC environments.

Triacs Replacement Considerations

Check for direct pin-compatible replacements within the same voltage and current class. Verify that any substitute maintains the same TO-220-2 package dimensions and thermal resistance characteristics. Ensure the replacement device meets or exceeds the 35 mA gate trigger current requirement.
