Q2004V4TP

Triacs Overview

The Littelfuse Q2004V4TP is a bidirectional triac from the Teccor Qxx04xx series, designed for general-purpose AC power control. It features a 600 V rated repetitive off-state voltage and conducts an RMS on-state current of 4 A. The device utilizes a TO-251-3 (DPAK) surface-mount package with three leads. Key electrical parameters include a maximum holding current of 30 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 25 mA to 50 mA. It operates within a temperature range of -40°C to +125°C and exhibits a typical on-state voltage of 1.6 V.

Triacs Feature Summary

• Surface-mount DPAK package design facilitates automated assembly and compact PCB layouts.
• High surge current capability supports robust performance in inductive load switching applications.
• Sensitive gate structure allows direct interfacing with standard logic-level control circuits.

Triacs Applications

• Solid-state relays and motor speed controllers
• Lighting dimmers and phase-control circuits
• General-purpose AC power switching modules

Triacs Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the ordered component matches the exact voltage and current ratings required for the target circuit design. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Triacs Selection Notes

Select this component when a surface-mount triac with 600 V blocking capability and 4 A continuous current rating is required. Evaluate the thermal management needs for the TO-251-3 package under expected load conditions. Confirm that the gate trigger characteristics align with the driving circuit's output capabilities for reliable turn-on.

Triacs Part Context

This part belongs to the Teccor Qxx04xx family of bidirectional triacs manufactured by Littelfuse. The series offers various voltage and current combinations in standardized packages. The Q2004V4TP specifically addresses applications requiring moderate power handling in a compact surface-mount form factor.

Triacs Replacement Considerations

Consult the manufacturer's cross-reference guide for verified equivalent parts. Ensure any substitute maintains identical pinout configuration, voltage ratings, and package dimensions to guarantee mechanical and electrical compatibility without redesigning the host circuit board.
