Q4006VH3

Triacs Overview

The Q4006VH3 is a bidirectional TRIAC manufactured by Littelfuse Inc., designed for AC power control applications. It features a 400 V repetitive peak off-state voltage (VDRM) and an RMS on-state current (IT(RMS)) rating of 6 A. The device exhibits a maximum on-state voltage of 1.6 V at rated current, with a holding current maximum of 15 mA and a gate trigger current of 10 mA. Non-repetitive peak on-state current ratings are specified at 55 A and 65 A under different pulse conditions. The component complies with RoHS directives and is lead-free.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• Lead-free construction compliant with environmental directives
• High thermal stability suitable for industrial environments

Triacs Applications

• Solid-state relays
• Motor speed control systems
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific datasheet revision to confirm exact electrical tolerances and thermal characteristics before finalizing designs. Ensure that the selected package variant matches the intended PCB footprint and mounting requirements. Cross-reference the manufacturer's official documentation for any updates regarding compliance certifications or recommended soldering profiles to guarantee assembly reliability.

Triacs Selection Notes

Select this component when a bidirectional switch is required for low-to-medium power AC loads operating within a 400 V voltage range. Consider the 6 A current rating against expected load peaks and duty cycles. Evaluate the gate drive circuitry to ensure it can reliably supply the specified 10 mA trigger current while maintaining compatibility with the control logic levels used in the system design.

Triacs Part Context

This part belongs to the Qxx06xxh series of TRIACs from Littelfuse, which are engineered for general-purpose AC power switching. The series offers a balance of robust electrical performance and compact packaging options.
