Q2006DH4TP

Triacs Overview

The Littelfuse Q2006DH4TP is a bidirectional triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (IT(RMS)) of 6 A. The device operates within a temperature range of -40 °C to +125 °C and utilizes a TO-252-3 surface-mount package. Key electrical characteristics include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 10 mA. Non-repetitive peak on-state currents are specified at 55 A and 65 A, with an on-state voltage of 1.6 V and a leakage current of 10 µA.

Triacs Feature Summary

• Integrated thermal protection mechanism for enhanced reliability under surge conditions
• Surface-mount construction in a compact TO-252-3 package for automated assembly
• High dv/dt capability to prevent false triggering during rapid voltage transients

Triacs Applications

• Solid-state relay modules
• Lighting dimmer circuits
• Motor speed control systems

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout orientation and packaging type. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration. Ensure the ordering quantity aligns with the factory reel specifications provided in the product data sheet.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 6 A continuous current rating are required in a surface-mount form factor. Compare the 10 mA gate trigger current against circuit drive capabilities. Evaluate the thermal management requirements for the TO-252-3 package based on the expected load duty cycle and ambient operating temperature.

Triacs Part Context

This part belongs to the Qxx06xxH series of Alternistor TRIACs from Littelfuse. These devices integrate standard triac functionality with built-in thermal shutdown protection. The series is engineered for robust performance in consumer and industrial AC power switching environments where space constraints favor surface-mount technologies.

Triacs Replacement Considerations

Direct replacements include the Q4006DH4TP and Q4006DH4RP, which share identical electrical ratings and package dimensions. Verify that any substitute maintains the same thermal protection threshold and gate sensitivity specifications.
