Q8006DH4TP

Triacs Overview

The Littelfuse Q8006DH4TP is a bidirectional thyristor (TRIAC) from the Qxx06xxH series, designed for high-voltage AC power control applications. It features an 800 V repetitive off-state voltage rating and conducts a continuous RMS on-state current of 6 A. The device supports non-repetitive peak on-state currents of 80 A or 85 A depending on pulse duration. Key electrical characteristics include a maximum on-state voltage of 1.6 V, a holding current of up to 35 mA, and a gate trigger voltage of 1.3 V with a gate trigger current of 35 mA. The component exhibits a low off-state leakage current of 10 µA at rated voltage.

Triacs Feature Summary

• Bidirectional conduction capability for alternating current switching
• High voltage blocking performance suitable for mains-level circuits
• Robust thermal handling via surface-mount packaging

Triacs Applications

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

Triacs Procurement Notes

Verify the specific datasheet revision and exact non-repetitive current rating (80 A vs 85 A) against the manufacturer's official documentation before finalizing design specifications. Confirm that the H4TP suffix corresponds to the required tape-and-reel packaging format for automated assembly processes.

Triacs Selection Notes

Select this component when designing circuits requiring bidirectional switching with an 800 V voltage margin and 6 A continuous load capacity. Ensure the gate drive circuit can supply at least 35 mA to guarantee reliable triggering under all operating temperature conditions.

Triacs Part Context

This part belongs to the Qxx06xxH family of TRIACs manufactured by Littelfuse. These devices are engineered for general-purpose AC power control, offering a balance of high voltage blocking and moderate current handling in compact surface-mount packages.

Triacs Replacement Considerations

Consult Littelfuse official cross-reference guides for verified equivalents within the same voltage and current class. Do not substitute based solely on package compatibility without verifying gate trigger parameters.
