Q8010R5TP

Triacs Overview

The Littelfuse Q8010R5TP is a standard triac belonging to the Qxx10xx series, designed for general-purpose AC power control applications. It features an 800 V rated repetitive off-state voltage (VDRM) and supports a continuous on-state RMS current (It RMS) of 10 A. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package with an isolated tab. Key electrical characteristics include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 50 mA to 75 mA. Non-repetitive peak on-state currents are specified at 100 A and 120 A, while the on-state voltage is 1.6 V.

Triacs Feature Summary

• Provides bidirectional switching capability for AC load control in high-voltage environments
• Features an isolated mounting tab in a TO-220-2 package for simplified heatsinking and insulation
• Designed for robust operation across a wide industrial temperature range

Triacs Applications

• Solid-state relays requiring high voltage isolation
• Industrial motor speed control circuits
• Lighting dimmer switches for commercial loads

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number Q8010R5TP with official Littelfuse documentation. Confirm that the specific ordering suffix matches the required pin configuration and packaging style. Ensure compliance with relevant safety standards before integration into end-use equipment.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 10 A continuous current capacity are required. The TO-220-2 package is suitable for applications needing thermal isolation from the mounting surface. Verify that the gate drive circuit can supply the necessary trigger current levels for reliable turn-on under varying load conditions.

Triacs Part Context

This device is part of the Littelfuse Qxx10xx series of standard triacs. It shares similar physical dimensions and basic electrical parameters with other variants in the family, differentiated primarily by their voltage ratings and specific gate sensitivity requirements. The series is engineered for cost-effective AC power switching solutions.

Triacs Replacement Considerations

The Q8015R5 is listed as an alias or related part number in distributor databases. However, it specifies a 15 A RMS current rating compared to the 10 A rating of the Q8010R5TP. Substitution requires verification of thermal management capabilities and gate drive compatibility.
