Q6006F51

Triacs Overview

The Littelfuse Q6006F51 is a three-terminal triac belonging to the Q6006 series, designed for general-purpose AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 6 A. The device utilizes a TO-202AB (TO-220AB) flange mount package with three pins, facilitating efficient heat dissipation through direct mounting to a heatsink. Key electrical characteristics include a maximum holding current of 35 mA and a gate trigger current of 35 mA. It operates within a junction temperature range of -40 °C to +125 °C and exhibits a typical on-state voltage drop of 1.6 V at rated current.

Triacs Feature Summary

• Robust thermal management via flange-mount package design for high-power density applications
• High surge current capability suitable for inductive load switching
• Standardized pinout compatible with common TO-220AB mounting hardware

Triacs Applications

• Solid-state relays and contactors
• Industrial motor speed control circuits
• Lighting dimmer modules for commercial fixtures

Triacs Procurement Notes

Verify the specific suffix F51 against manufacturer datasheets to confirm exact gate characteristics and packaging variations. Ensure compatibility with existing PCB or chassis mounting holes for the TO-202AB form factor. Confirm insulation class requirements if isolation from the heatsink is necessary, as the main terminal 2 is typically connected to the flange.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 6 A continuous current rating are required in a standard TO-220AB package. Consider the 35 mA gate trigger requirement for driver circuit design. Evaluate thermal resistance values relative to the expected ambient temperature and duty cycle to determine appropriate heatsinking solutions for reliable operation.

Triacs Part Context

This part belongs to the Littelfuse Teccor Q6006 family of triacs, which are widely used in industrial and consumer power control. The Q6006 series offers various voltage ratings and package options, with the F51 variant specifically denoting the 600 V version in the TO-202AB flange mount configuration.

Triacs Replacement Considerations

Direct replacements may include other 600 V, 6 A triacs in TO-220AB packages such as the STMicroelectronics TCA606 or similar equivalents from other manufacturers, provided gate trigger specifications and thermal characteristics match.
