Q8025R5

Triacs Overview

The Littelfuse Q8025R5 is a bidirectional triac rated for 800 V repetitive off-state voltage and 15 A RMS on-state current. It features a gate trigger current of 50 mA and a maximum holding current of 70 mA. The device operates within a junction temperature range of -40 °C to +125 °C and utilizes a TO-220-2 through-hole package.

Triacs Feature Summary

• Bidirectional switching capability for AC power control applications
• High thermal stability with operation up to +125 °C
• Robust construction in a standard TO-220-2 insulated package

Triacs Applications

• AC motor speed control circuits
• Solid-state relay designs
• Lighting dimmer switches

Triacs Procurement Notes

Verify the specific suffix 'R5' against the manufacturer's official datasheet to confirm pinout and insulation characteristics. Ensure the ordering quantity aligns with factory packaging constraints, as minimum order quantities may apply for this component series.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 15 A continuous current are required in a through-hole format. Compare gate sensitivity requirements against the 50 mA trigger specification to ensure compatibility with the driving circuitry.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx15xx series of high-power triacs. It is designed for industrial and consumer applications requiring reliable AC switching. The TO-220-2 package provides mechanical robustness and ease of heatsinking for thermal management.

Triacs Replacement Considerations

Consult the official Littelfuse replacement guide for direct equivalents. Verify that any substitute maintains the same voltage rating, current capacity, and package dimensions to ensure board compatibility.
