Q8010R5

Triacs Overview

The Littelfuse Q8010R5 is a bidirectional triac designed for AC power control applications. It features an 800 V rated repetitive off-state voltage (VDRM) and supports a continuous RMS on-state current 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. 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 under different conditions.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• Robust thermal performance suitable for high-temperature environments up to 125°C
• Standardized TO-220-2 leaded package for secure mounting

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuitry

Triacs Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct packaging and variant selection. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Validate that the TO-220-2 footprint matches the target PCB design requirements. Ensure supply chain sources provide authentic Littelfuse components with traceable manufacturing data.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 10 A continuous current rating are required for AC load management. Consider the 50 mA holding current specification to ensure reliable latching in low-current hold scenarios. Evaluate the TO-220-2 package constraints for thermal dissipation needs in the final assembly environment.

Triacs Part Context

This part belongs to the Qxx10xx series of thyristors manufactured by Littelfuse. The series provides standardized solutions for general-purpose AC power switching. The Q8010R5 specifically addresses applications requiring moderate current handling with high voltage isolation capabilities in a traditional through-hole form factor.

Triacs Replacement Considerations

The Q8015R5 is documented as having the alias Q8015R5TP, indicating potential cross-reference relationships within the manufacturer's lineup. Verify pinout compatibility and thermal resistance differences before substituting with other triacs in the same voltage class.
