Q6006DH3TP

Triacs Overview

The Littelfuse Q6006DH3TP is a bidirectional TRIAC belonging to the Teccor Qxx06xH series, designed for general-purpose AC power control applications. It features a 400 V rated repetitive off-state voltage (VDRM) and supports an RMS on-state current (ITRMS) of 6 A. The device utilizes a TO-252 (DPAK) surface-mount package with three terminals. Key electrical characteristics include a maximum holding current of 15 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 10 mA. It exhibits a typical on-state voltage of 1.6 V and a non-repetitive peak on-state current capability ranging from 55 A to 65 A depending on pulse duration.

Triacs Feature Summary

• Surface-mount TRIAC design in a compact TO-252 package for automated PCB assembly
• High thermal reliability suitable for industrial and consumer AC power switching
• Standard gate sensitivity with defined trigger voltage and current thresholds

Triacs Applications

• Solid-state relays and motor speed controls
• Lighting dimmers and soft-start circuits
• General AC load switching in household appliances

Triacs Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's latest datasheet to confirm lead-free status and tape-and-reel packaging specifications. Ensure the ordering part number matches the required voltage and current ratings for the target application circuit. Cross-reference with authorized distributors to confirm current availability and authenticity.

Triacs Selection Notes

Select this component when a surface-mount TRIAC with 400 V blocking capability and 6 A continuous current rating is required. Compare against through-hole alternatives like the Q6006LTH if higher thermal dissipation or different mounting styles are needed. Verify that the gate drive circuitry can supply at least 10 mA to ensure reliable triggering under all operating conditions.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx06xH family of high-reliability TRIACs. The Q6006DH3TP specifically denotes the 400 V variant packaged in a TO-252 outline. It shares functional similarities with other members of the series but differs in voltage rating and physical footprint compared to higher-voltage or through-hole versions.

Triacs Replacement Considerations

Direct pin-compatible replacements within the same package may include other 400 V, 6 A TRIACs in TO-252 packages from Littelfuse or competitors, provided gate parameters and thermal characteristics are compatible.
