Q6004V4

Triacs Overview

The Littelfuse Q6004V4TP is a bidirectional triac belonging to the Teccor Qxx04xx series, designed for general-purpose AC power control applications. It features a TO-251-3 (SMD) package with through-hole compatibility characteristics in its family variants, though this specific suffix denotes surface mount. Key electrical parameters include a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (It RMS) of 4 A. The device exhibits a maximum on-state voltage of 1.6 V and a gate trigger voltage (Vgt) of 2.5 V. It operates within a temperature range of -40°C to +125°C.

Triacs Feature Summary

• Bidirectional switching capability for AC load control
• High thermal stability with extended operating temperature range
• Low gate sensitivity for simplified driver interface

Triacs Applications

• Lighting dimmers
• Motor speed controls
• Solid state relays

Triacs Procurement Notes

Verify the exact suffix (e.g., TP vs RP) against the Bill of Materials, as packaging and mounting style differ significantly between tube and reel formats. Confirm RoHS compliance status via the manufacturer's latest datasheet revision. Ensure the ordering quantity aligns with the factory minimum order quantity specified by the distributor.

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 the 1.6 V on-state voltage against alternative triacs to evaluate conduction losses. Verify that the gate trigger current requirements of the driving circuit fall within the specified 25 mA to 50 mA range for reliable turn-on.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx04xx series of standard triacs. The series offers various packages including TO-92, TO-220, and SMD types. The Q6004V4TP specifically utilizes the TO-251-3 package, distinguishing it from the leaded Q6004V4T or the reel-packaged Q6004D4RP variants within the same electrical specification family.

Triacs Replacement Considerations

Direct pin-compatible replacements may include the Q6004D4RP (same electrical specs, different package/reel). For through-hole needs, the Q6004V4T is available. Verify that any substitute maintains the 600 V rating and 4 A current capacity.
