Q2004D3TP

Triacs Overview

The Littelfuse Q2004D3TP is a bidirectional triac from the Teccor Qxx04xx series, designed for general-purpose AC power control applications. 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 is housed in a TO-252-3 surface-mount package. Key electrical parameters include a maximum gate trigger voltage (Vgt) of 2 V and a gate trigger current (Igt) ranging from 10 mA to 25 mA. The holding current (Ih) is specified at a maximum of 20 mA, with an on-state voltage of 1.6 V. It operates within a temperature range of -40 °C to +110 °C.

Triacs Feature Summary

• Bidirectional conduction capability for AC load switching
• Surface-mount TO-252-3 packaging for automated assembly
• High sensitivity gate triggering characteristics

Triacs Applications

• General purpose AC motor speed control
• Solid state relay output stages
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific datasheet revision and ordering suffixes directly with Littelfuse or authorized distributors to ensure component authenticity. Confirm that the TO-252-3 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Triacs Selection Notes

Select this component when a low-voltage (200 V), 4 A AC switch is required in a compact surface-mount form factor. Ensure the application voltage does not exceed the 200 V rating and that the gate drive circuit can supply the necessary trigger current within the specified limits.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx04xx series of high-sensitivity triacs. The series is characterized by its robust construction and suitability for various industrial and consumer AC power control applications requiring reliable switching performance in small packages.

Triacs Replacement Considerations

Direct replacements must match the 200 V rating, 4 A current capacity, and TO-252-3 package. Verify gate sensitivity and thermal characteristics against the original design specifications to ensure compatibility.
