L4004D5RP

Triacs Overview

The L4004D5RP is a four-quadrant logic level TRIAC manufactured by Littelfuse under the Teccor brand. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 4 A. The device utilizes a TO-220 package with three pins and includes an isolated case configuration. Key electrical characteristics include a maximum holding current of 30 mA, a gate trigger current ranging from 25 mA to 50 mA, and a gate trigger voltage of 2.5 V. The component exhibits a non-repetitive peak on-state current capability of 46 A or 55 A depending on specific conditions, with an on-state voltage of 1.6 V and a low off-state leakage current of 10 uA.

Triacs Feature Summary

• Four-quadrant logic level triggering for simplified gate drive circuitry
• Isolated case construction for enhanced thermal and electrical management
• High surge current handling capability for robust power control

Triacs Applications

• Solid state relays
• Motor speed control circuits
• Lighting dimmer applications

Triacs Procurement Notes

Verify the exact suffix D5RP against official Littelfuse documentation to confirm pinout and isolation specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet. Check for obsolescence notices as this component series may have lifecycle changes. Ensure the procurement channel provides genuine parts with traceable manufacturing dates.

Triacs Selection Notes

Select this component when a 400V rating and 4A continuous current are required in a TO-220 isolated package. The logic-level gate sensitivity simplifies interface with microcontrollers or low-power drivers. Verify that the 30 mA holding current meets the load requirements to prevent unintended turn-off during operation.

Triacs Part Context

This part belongs to the Lxx04xx and Qxx04xx series of TRIACs produced by Littelfuse. These devices are designed for general-purpose AC power switching applications. The Teccor brand indicates a focus on high-reliability thyristor solutions for industrial and consumer electronics markets.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic replacements must match the 400V voltage rating, 4A current capacity, and TO-220 isolated package form factor.
