Q8006VH4TP

Triacs Overview

The Littelfuse Q8006VH4TP is a bidirectional triac belonging to the Qxx06xxH series, designed for through-hole mounting in TO-251-3 packages. It features an RMS on-state current of 6 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device exhibits a maximum holding current of 35 mA, with gate trigger voltage and current ratings of 1.3 V and 35 mA respectively. On-state voltage is specified at 1.6 V, while leakage current remains at 10 uA under VDRM conditions. Non-repetitive peak currents are rated at 80 A and 85 A. Operating temperatures range from -40 C to +125 C.

Triacs Feature Summary

• Bidirectional switching capability suitable for AC control applications
• High voltage blocking performance with 800 V rating
• Robust thermal operation across extended temperature ranges

Triacs Applications

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

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number Q8006VH4TP with official Littelfuse documentation. Confirm package type matches TO-251-3 specifications. Ensure compliance with RoHS and REACH requirements as indicated in product attributes. Validate supplier authorization status before acquisition.

Triacs Selection Notes

Select this component when 6 A RMS current handling and 800 V blocking voltage are required in a compact surface-mount compatible footprint. Consider the 35 mA gate drive requirement for circuit interface design. Evaluate thermal management needs given the 125 C maximum operating temperature limit and TO-251-3 package constraints.

Triacs Part Context

This triac belongs to the Qxx06xxH family, characterized by high voltage ratings and specific gate sensitivity. The 'H' suffix typically denotes high voltage variants within the series. It serves as a solid-state alternative to mechanical relays in AC power control systems, offering faster switching and longer operational life compared to electromechanical counterparts.

Triacs Replacement Considerations

Direct substitutes include other 800 V, 6 A bidirectional triacs in TO-251-3 packages. Verify matching electrical parameters such as holding current and gate trigger thresholds. Ensure physical pinout compatibility and thermal resistance characteristics align with existing board designs.
