Q4006DH4RP

Triacs Overview

The Littelfuse Q4006DH4RP is a bidirectional triac from the Qxx06xxH series, designed for surface-mount applications in the TO-252-3 package. 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 exhibits a maximum holding current of 35 mA and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a gate trigger voltage of 1.3 V, a gate trigger current of 10 mA, and an on-state voltage of 1.6 V. Leakage current at VDRM is specified at 10 uA.

Triacs Feature Summary

• High reliability construction suitable for demanding industrial environments
• Sensitive gate configuration enabling efficient triggering with low drive power
• Robust thermal performance supporting operation up to 125°C junction temperature

Triacs Applications

• Solid state relays requiring compact surface-mount integration
• Industrial motor control circuits utilizing high-reliability thyristors
• General purpose AC power switching applications

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number Q4006DH4RP with official Littelfuse documentation. Confirm compliance with RoHS and REACH standards as indicated in the datasheet. Ensure the TO-252-3 package matches design requirements. Validate that the specific suffix RP corresponds to the reel packaging format required for assembly processes.

Triacs Selection Notes

Select this component when a 400 V rating and 6 A continuous current capacity are required in a surface-mount form factor. The sensitive gate characteristics (1.3 V / 10 mA) simplify driver circuit design compared to standard gate devices. Consider the TO-252-3 package for PCB space constraints while ensuring adequate thermal management for the 6 A load current.

Triacs Part Context

This device belongs to the Qxx06xxH series of bidirectional triacs manufactured by Littelfuse. The series is characterized by high reliability standards and is intended for general-purpose AC power control. The 'H' designation typically denotes specific reliability or feature enhancements within the broader Qxx06xx family.

Triacs Replacement Considerations

Direct substitutes within the same series include Q4006DH4, which shares identical electrical ratings but may differ in packaging or lead-free status. Verify pinout compatibility and thermal resistance specifications before substituting.
