Q2004D4RP

Triacs Overview

The Littelfuse Q2004D4RP is a Teccor brand triac belonging to the Qxx04xx series, designed for surface-mount applications in the TO-252-3 package. It features a rated repetitive off-state voltage (VDRM) of 200 V and an on-state RMS current (It RMS) of 4 A. The device supports a non-repetitive peak on-state current ranging from 46 A to 55 A, with a maximum holding current (Ih) of 30 mA. Gate triggering requirements include a voltage (Vgt) of 2.5 V and a current (Igt) between 25 mA and 50 mA. It operates within a temperature range of -40°C to +125°C, exhibits an on-state voltage of 1.6 V, and maintains a leakage current of 10 µA at VDRM.

Triacs Feature Summary

• Bidirectional conduction capability for AC power control applications
• Surface-mount construction utilizing the TO-252-3 package for automated assembly
• High thermal stability supporting operation up to +125°C junction temperature

Triacs Applications

• Lighting dimmers and control circuits
• Solid-state relays
• Motor speed control systems

Triacs Procurement Notes

Verify the specific manufacturer part number against official Littelfuse documentation to confirm availability and exact specifications. Ensure that any ordering suffixes correspond to the required packaging format, such as reel quantities, without altering the electrical characteristics of the component.

Triacs Selection Notes

Select this component based on the 200 V voltage rating and 4 A current capacity requirements. Confirm compatibility with the TO-252-3 footprint and ensure the gate drive circuit can supply the specified 2.5 V and 25 mA trigger parameters for reliable switching.

Triacs Part Context

This device is part of the Teccor Qxx04xx family of triacs, which are engineered for general-purpose AC power switching. The series offers standardized electrical characteristics across different voltage ratings, facilitating design scalability while maintaining consistent package dimensions and thermal performance profiles.

Triacs Replacement Considerations

Direct substitutes may include other 200 V, 4 A triacs in the TO-252-3 package from Littelfuse or equivalent manufacturers, provided they meet the same It RMS, VDRM, and Igt specifications.
