Triacs datasheet and documents for Q4004LTTP

Q4004LTTP

Triacs Overview

The Littelfuse Q4004LTTP is a bidirectional triac from the Teccor Quadrac series, designed for AC switching and phase control. It integrates a diac trigger within the package to simplify circuit design. The device features a 4 A RMS on-state current rating and supports a repetitive peak off-state voltage of 400 V. Packaged in a TO-220 through-hole configuration with three pins, it operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum gate trigger current of 10 mA, a peak on-state voltage of 1.6 V, and a surge current rating of 55 A.

Triacs Feature Summary

Integrated diac trigger eliminates the need for discrete components
Electrically isolated TO-220 package reduces assembly complexity
Glass-passivated junctions ensure parameter stability

Triacs Applications

AC speed controls
Temperature modulation controls
Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and isolation ratings. Ensure the procurement source provides valid RoHS compliance data. Cross-reference the part number with manufacturer databases to confirm current production status and availability constraints.

Triacs Selection Notes

Select this component for applications requiring integrated triggering without external snubber networks. Verify that the 400 V voltage rating meets the system's peak reverse voltage requirements. Confirm that the TO-220 package thermal characteristics are sufficient for the expected heat dissipation in the target environment.

Triacs Part Context

This part belongs to the QxxxxLTx series of Teccor Quadrac devices manufactured by Littelfuse. These devices combine a triac and a diac in a single package to streamline AC phase control designs. The series offers various current and voltage ratings within the TO-220 form factor.
