L4004V3TP

Triacs Overview

The Littelfuse L4004V3TP is a sensitive gate triac from the Lxx04xx series, rated for 4 A RMS on-state current and 400 V repetitive peak off-state voltage. It features a TO-251-3 (DPAK) surface-mount package with three leads. Key electrical parameters include a maximum holding current of 5 mA, a gate trigger voltage of 2 V, and a gate trigger current of 3 mA. The device exhibits a forward on-state voltage of 1.6 V and a maximum off-state leakage current of 5 uA at VDRM. It operates within a temperature range of -40 C to +110 C and supports non-repetitive surge currents of 33 A or 40 A.

Triacs Feature Summary

• Sensitive gate design enabling control in Quadrants I, II, III, and IV for compatibility with digital circuitry.

Triacs Applications

• AC power control circuits requiring four-quadrant gating.

Triacs Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm packaging details and any functional variations. Ensure the procurement documentation explicitly references the Littelfuse L4004V3TP part number to avoid confusion with similar devices in the L4004 family that may use different packages or ratings.

Triacs Selection Notes

Select this component when a surface-mount solution is required for low-current AC switching applications. The sensitive gate characteristics make it suitable for direct interface with microcontrollers or logic gates. Confirm that the TO-251-3 package thermal performance meets the system's heat dissipation requirements under continuous load conditions.

Triacs Part Context

This device belongs to the Teccor brand line of sensitive triacs manufactured by Littelfuse. The L4004 series offers current capabilities ranging from 0.8 A to 8 A with voltage ratings up to 600 V. The L4004V3TP specifically addresses the need for compact, surface-mountable thyristors in modern electronics where space constraints and automated assembly are critical factors.

Triacs Replacement Considerations

Direct replacements must match the 4 A/400 V rating and TO-251-3 package. Verify gate sensitivity and quadrant operation compatibility before substituting with other manufacturers' sensitive triacs.
