Q6006RH3

Triacs Overview

The Littelfuse Q6006RH3 is a bidirectional triac designed for AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 6 A. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical characteristics include a maximum holding current of 35 mA, a gate trigger current of 35 mA, and a gate trigger voltage of 1.3 V. The on-state voltage drop is specified at 1.6 V, with a non-repetitive peak on-state current capability of 80 A or 85 A depending on the pulse duration. The component utilizes a surface-mount SMTO-263-2 package.

Triacs Feature Summary

• High thermal stability supporting operation up to +125 °C
• Robust surge handling with high non-repetitive peak current ratings
• Low gate sensitivity for simplified driver circuit design

Triacs Applications

• Solid-state relays
• AC motor speed controls
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm pinout and packaging variations. Ensure the selected variant matches the required thermal management strategy for the target application environment. Cross-reference datasheet revisions to confirm compliance with current RoHS and REACH standards before finalizing procurement specifications.

Triacs Selection Notes

Select this component based on the 600 V blocking voltage and 6 A continuous current requirements. Evaluate the thermal resistance of the SMTO-263-2 package against the expected heat dissipation in the system. Confirm that the gate drive circuit can supply the necessary 35 mA trigger current reliably across the full operating temperature range.

Triacs Part Context

This part belongs to the Littelfuse Teccor series of thyristors, specifically engineered for general-purpose AC switching. The Q6006RH3 variant provides a balance of current handling and voltage blocking suitable for consumer electronics and industrial control panels requiring compact surface-mount solutions.

Triacs Replacement Considerations

Direct replacements must match the 600 V / 6 A rating and SMTO-263-2 footprint. Verify equivalent gate trigger characteristics and thermal performance from other manufacturers if Littelfuse stock is unavailable.
