L4004R5TP

Triacs Overview

The Littelfuse L4004R5TP is a Teccor brand triac belonging to the Lxx04xx series, designed for general-purpose AC power control applications. It features a TO-220-2 package with through-hole mounting and is supplied in tube packaging. The device supports a repetitive peak off-state voltage (VDRM) of 400 V and an RMS on-state current (IT(RMS)) of 4 A. Key electrical parameters include a maximum gate trigger current (Igt) of 5 mA, a holding current (IH) maximum of 5 mA, and a non-repetitive peak on-state current rating of 40 A. The component operates within a junction temperature range of -40°C to +125°C, exhibits a low on-state voltage of 1.6 V, and maintains a low off-state leakage current of 5 µA.

Triacs Feature Summary

• Sensitivity class optimized for low-power gate drive circuits with a maximum gate trigger current of 5 mA.
• Robust thermal management capability enabled by the TO-220-2 through-hole package design.
• High surge current handling capacity suitable for inductive load switching environments.

Triacs Applications

• Solid-state relay modules requiring compact thyristor switching elements
• Lighting dimmer circuits for resistive and inductive loads
• Motor speed control systems for small appliances

Triacs Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm tube packaging specifications and exact pinout configuration. Ensure compatibility with existing PCB footprint dimensions and thermal dissipation requirements before finalizing procurement decisions.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 4 A continuous current rating are required in a standard TO-220-2 form factor. The 5 mA gate sensitivity makes it suitable for direct interface with logic-level drivers or optocouplers without additional amplification stages.

Triacs Part Context

This part belongs to the Littelfuse Teccor Lxx04xx series of four-layer triacs. The series is characterized by high reliability and standardized electrical parameters for general industrial and consumer AC power control applications.

Triacs Replacement Considerations

Cross-reference with other Lxx04xx series variants such as L4004L5TP for potential packaging differences. Verify that substitute parts maintain identical voltage, current, and gate sensitivity ratings to ensure circuit functionality.
