Q6025L656

Triacs Overview

The Littelfuse Q6025L656 is an Alternistor TRIAC designed for high-reliability AC switching applications. It features a 600 V rated repetitive off-state voltage and conducts a continuous RMS on-state current of 25 A. The device utilizes an isolated TO-220AB package, providing electrical isolation between the leads and the mounting surface to simplify heat sink integration without external insulators. Key gate parameters include a maximum DC gate trigger current of 80 mA and a maximum DC gate trigger voltage of 1.3 V. The component operates within a junction temperature range from -40 °C to +150 °C and exhibits a typical on-state voltage of 1.8 V.

Triacs Feature Summary

• Electrically isolated TO-220AB package eliminates the need for separate insulators and mounting hardware
• High thermal stability with a maximum operating junction temperature of +150 °C
• Glass-passivated junctions ensure long-term parameter stability and reliability

Triacs Applications

• Industrial motor speed controls
• Temperature modulation systems
• Lighting control circuits requiring noise immunity

Triacs Procurement Notes

Verify the specific suffix '656' against official Littelfuse documentation to confirm exact gate characteristics and packaging options. Ensure the selected variant matches the required isolation voltage and thermal management specifications for the target application environment.

Triacs Selection Notes

Select this component when high current capacity and electrical isolation are required in a single package. The 25 A rating suits moderate power AC loads, while the isolated case simplifies mechanical assembly compared to non-isolated alternatives.

Triacs Part Context

This part belongs to the Littelfuse Alternistor series, which integrates triac functionality with enhanced isolation features. The Q6025L656 shares the core 25 A / 600 V architecture with other members of the Q6025Lxx family, differentiated primarily by gate sensitivity and specific manufacturing revisions.

Triacs Replacement Considerations

Direct replacements within the same series include Q6025L6TP and Q6025L665V. Verify pinout compatibility and gate trigger requirements before substituting.
