L4004L5

Triacs Overview

The Littelfuse L4004L5 is a four-quadrant logic level triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an RMS on-state current (IT(RMS)) of 4 A. The device operates within a junction temperature range of -40 °C to +110 °C. Key electrical characteristics include a maximum gate trigger current (IGT) of 5 mA, ensuring compatibility with low-power logic circuits. The component utilizes a TO-220-2 package for through-hole mounting.

Triacs Feature Summary

• Logic level sensitivity allows direct drive from standard logic families without additional amplification.

Triacs Applications

• AC motor speed control
• Solid state relays
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and isolation requirements. Confirm RoHS compliance status via the manufacturer's latest datasheet before integration into regulated designs.

Triacs Selection Notes

Select this component when a 400 V rating and 4 A continuous current are required in a TO-220-2 package. Ensure the driving circuit can supply the specified 5 mA gate trigger current reliably across the full operating temperature range.

Triacs Part Context

This part belongs to the Teccor Lxx04xx series of thyristors manufactured by Littelfuse. The series is characterized by high reliability and standardized electrical parameters for general-purpose AC switching applications.

Triacs Replacement Considerations

Consult Littelfuse substitution guides for equivalent logic-level triacs. Verify that any alternative maintains the 400 V blocking voltage and 4 A current capacity.
