QJ4006DH2TP

Triacs Overview

The QJ4006DH2TP is a bidirectional triac manufactured by Littelfuse, designed for AC power switching applications. It features an RMS on-state current of 6 A and a rated repetitive off-state voltage (VDRM) of 400 V. The device exhibits a maximum on-state voltage of 1.4 V and a gate trigger voltage (VGT) of 1.3 V with a gate trigger current (IGT) of 35 mA. Leakage current at VDRM is limited to 10 uA. It operates within a temperature range of -40°C to +150°C and is housed in a TO-252-3 surface-mount package.

Triacs Feature Summary

• Bidirectional AC switching capability for phase control
• Glass-passivated junctions for parameter stability
• Surface-mount TO-252-3 packaging for automated assembly

Triacs Applications

• Lighting controls
• Speed controls
• Temperature modulation controls

Triacs Procurement Notes

Verify the specific suffix 'H2' against official Littelfuse documentation to confirm exact electrical tolerances and marking codes, as variations exist within the QJxx06xH series. Ensure the component meets RoHS compliance requirements for the intended market. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing specifications and lead times.

Triacs Selection Notes

Select this component when a 400 V rating is sufficient for the AC line voltage, offering cost efficiency over higher-rated 600 V alternatives. The TO-252-3 package facilitates high-volume SMT production. Verify that the 6 A RMS current capacity aligns with the load requirements, considering derating factors for ambient temperatures exceeding standard test conditions.

Triacs Part Context

This part belongs to the QJxx06xH series of Teccor brand triacs from Littelfuse. These devices are engineered for general-purpose AC switching where noise immunity is required. The series utilizes glass-passivated junction technology to ensure long-term reliability and stable parameters across the operating temperature range.

Triacs Replacement Considerations

Direct substitutes include other 6 A, 400 V triacs in TO-252 packages such as the QJ4006DH3TP, provided pinout compatibility and thermal characteristics match the design constraints.
