Q6004V3

Triacs Overview

The Littelfuse Q6004V3 is a Triac belonging to the Teccor Qxx04xx series, designed for general-purpose AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 4 A. The device is housed in a TO-252-3 (DPAK) surface-mount package with three terminals. Key electrical characteristics include a maximum gate trigger current (Igt) of 10 mA and a peak on-state voltage of 1.6 V. It operates within a junction temperature range of -40°C to +125°C and supports non-repetitive surge currents up to 55 A.

Triacs Feature Summary

• High thermal stability with a maximum operating junction temperature of 125°C
• Sensitive gate drive capability requiring a maximum trigger current of 10 mA
• Robust surge handling with a 55 A non-repetitive peak on-state current rating
• Surface-mount DPAK packaging optimized for automated PCB assembly

Triacs Applications

• Solid-state relays and motor speed controllers
• Lighting dimmers and soft-start circuits
• General-purpose AC load switching in consumer appliances

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout orientation and exact electrical tolerances. Ensure the procurement channel provides genuine components with traceable manufacturing dates to avoid counterfeit devices. Confirm RoHS compliance status if required by your assembly specifications.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 4 A continuous current are required in a compact surface-mount form factor. Compare against through-hole alternatives like the Q6004L series if higher thermal dissipation or mechanical robustness is needed. Verify that the gate drive circuit can supply at least 10 mA to ensure reliable triggering under all load conditions.

Triacs Part Context

The Q6004V3 is part of the broader Teccor Qxx04xx family of Triacs manufactured by Littelfuse. This series is widely used in industrial and consumer electronics for AC power regulation. The 'V' suffix typically denotes the specific surface-mount package variant within the 600 V, 4 A performance class.

Triacs Replacement Considerations

Direct replacements include other 600 V, 4 A Triacs in TO-252 packages from Littelfuse or competitors such as STMicroelectronics or Vishay. Ensure equivalent gate trigger characteristics and thermal resistance values are matched during substitution.
