Q6006DH4TP

Triacs Overview

The Littelfuse Q6006DH4TP is a bidirectional triac from the Qxx06xxH series, rated for 600V VDRM and 6A IT(RMS). It features a TO-252 (DPAK-3) surface-mount package with Main Terminal 2 connected to the case. Key electrical parameters include a maximum holding current of 35 mA, gate trigger voltage of 1.3 V, and gate trigger current of 35 mA. The device operates within a temperature range of -40°C to +125°C, with an on-state voltage of 1.6 V and leakage current of 10 uA at VDRM.

Triacs Feature Summary

• Integrated Alternistor technology designed for high reliability and noise immunity in AC switching applications.
• Case-connected Main Terminal 2 facilitates efficient thermal dissipation through direct PCB mounting.
• Glass-passivated junctions ensure long-term parameter stability and protection against environmental stress.

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm tape-and-reel packaging requirements. Ensure the ordering quantity aligns with the factory pack size of 750 units. Confirm RoHS compliance status directly with the supplier documentation prior to procurement.

Triacs Selection Notes

Select this component when a 600V blocking capability and 6A continuous current are required in a compact SMD form factor. The TO-252 package is suitable for applications needing moderate power density. Verify that the 35 mA gate drive requirement matches the available control circuit output capabilities.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx06xxH series of Alternistor TRIACs. These devices are engineered for general-purpose AC power control, offering robust performance in residential and industrial electronics where reliable switching and thermal management are critical.

Triacs Replacement Considerations

The Q6006DH4 is the leaded through-hole equivalent in the same family. For direct pin-compatible replacements, verify datasheets for other 600V 6A TRIACs in TO-252 packages from Littelfuse or competitors, ensuring identical gate trigger characteristics and thermal resistance values.
