Q8010RH5

Triacs Overview

The Littelfuse Q8010RH5 is a high-reliability bidirectional triac designed for robust power control applications. It features an 800 V rated repetitive off-state voltage 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-220AB three-pin through-hole package. Key electrical characteristics include a maximum holding current of 50 mA, a gate trigger voltage of 1.5 V, and a gate trigger current of 50 mA. It exhibits a maximum on-state voltage of 1.6 V and a leakage current of 10 µA at the rated voltage.

Triacs Feature Summary

• High reliability construction suitable for demanding industrial environments
• Robust thermal management via TO-220AB leaded package
• Bidirectional switching capability for AC power control circuits

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay (SSR) modules
• AC power regulation and switching circuits

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number with official Littelfuse documentation. Confirm that the specific suffix indicates the required high-reliability variant and package style. Ensure compliance with relevant safety standards and RoHS directives before integration into final assemblies.

Triacs Selection Notes

Select this component when high-reliability AC switching is required in through-hole designs. Compare the 10 A current rating and 800 V blocking voltage against circuit demands. Evaluate the thermal requirements of the TO-220AB package relative to the expected heat dissipation in the target application environment.

Triacs Part Context

This component belongs to the Littelfuse Teccor series of thyristors. It serves as a specialized high-reliability variant within the broader Q8010 family, distinguished by its specific packaging and reliability ratings compared to standard commercial grade equivalents.

Triacs Replacement Considerations

Direct substitutes may include other 800V 10A triacs in TO-220 packages from Littelfuse or competitors. Verify matching electrical parameters such as holding current and gate trigger specifications to ensure functional compatibility without redesigning the drive circuitry.
