Q2004V3TP

Triacs Overview

The Littelfuse Q2004V3TP is a bidirectional triac designed for AC power control applications. It features a rated repetitive peak off-state voltage (VDRM) of 200 V and an RMS on-state current (It RMS) of 4 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-251-3 (DPAK) surface-mount package. Key electrical characteristics include a maximum gate trigger voltage (Vgt) of 2 V, a holding current (Ih) of 20 mA, and a non-repetitive peak on-state current capability of 46 A or 55 A depending on the specific test condition. The component exhibits a typical on-state voltage of 1.6 V and a low leakage current of 10 µA at rated voltage.

Triacs Feature Summary

• Surface-mount DPAK packaging facilitates automated assembly and compact circuit board layouts.
• High thermal stability supports operation in demanding industrial environments up to 125°C.
• Robust surge current handling capability protects against transient load conditions.

Triacs Applications

• Solid-state relay output stages
• Lighting dimmer circuits
• Motor speed control systems

Triacs Procurement Notes

Verify the specific datasheet revision and ordering suffixes to ensure compatibility with required lead times and compliance standards such as RoHS. Confirm that the TO-251-3 footprint matches the target PCB design. Cross-reference official Littelfuse documentation for any updates regarding automotive qualification status or recommended soldering profiles.

Triacs Selection Notes

Select this component when a 200 V rating is sufficient for the application, offering cost advantages over higher voltage variants. Ensure the gate drive circuit can supply the specified 10 mA to 25 mA trigger current. Consider the thermal resistance of the TO-251-3 package for heat dissipation requirements in enclosed spaces compared to through-hole alternatives.

Triacs Part Context

This part belongs to the Teccor Qxx04xx series of general-purpose triacs from Littelfuse. The series provides standardized performance for AC switching tasks. The 'V' suffix typically denotes the voltage rating class, while '3TP' indicates the specific package type and tape-and-reel packaging configuration for high-volume manufacturing.

Triacs Replacement Considerations

Direct replacements must match the 200 V / 4 A specification and TO-251-3 package. Verify pinout compatibility and thermal characteristics. Check manufacturer cross-reference lists for equivalent parts with identical electrical parameters and mounting dimensions.
