Q8010LH568

Triacs Overview

The Littelfuse Q8010LH568 is a high-voltage bidirectional triac belonging to the Qxx10xx series, designed for robust power control applications. It features an 800V repetitive peak off-state voltage and handles a 10A on-state RMS current. The device utilizes a gate trigger configuration with specified currents of 50mA for both positive and negative triggering modes. Packaged in a TO-220-2 insulated tab format, it ensures electrical isolation from the heatsink. Key electrical characteristics include a maximum holding current of 10mA and a low on-state voltage drop of 1.6V at rated current, facilitating efficient thermal management in industrial switching circuits.

Triacs Feature Summary

• High voltage blocking capability suitable for demanding AC line applications
• Robust 10A continuous current handling for heavy loads
• Insulated tab package design for safe mounting without additional insulators

Triacs Applications

• Industrial motor speed control systems
• Solid state relays for high-power switching
• AC power regulation in heating elements

Triacs Procurement Notes

Verify the specific suffix LH568 against the official Littelfuse datasheet to confirm pinout orientation and insulation class. Ensure the procurement channel provides the original manufacturer's data sheet rather than third-party summaries. Confirm RoHS compliance status directly from the component marking or official documentation before integration into regulated assemblies.

Triacs Selection Notes

Select this component when an 800V rating is required for AC mains operation alongside 10A load capacity. The TO-220-2 package is appropriate for applications requiring direct heatsinking with electrical isolation. Compare the 50mA gate trigger sensitivity against microcontroller output capabilities to ensure reliable turn-on without excessive drive current requirements.

Triacs Part Context

This part belongs to the Qxx10xx family of high-voltage triacs from Littelfuse. These devices are engineered for general-purpose AC power control where high voltage withstand and moderate current capacity are critical. The series offers standardized pinouts and thermal characteristics to simplify replacement in existing industrial designs.

Triacs Replacement Considerations

Direct replacements must match the 800V/10A/TO-220-2 specifications. Verify that substitute parts maintain the same gate trigger current characteristics and insulation properties to ensure circuit compatibility.
