Q8010LH5TP

Triacs Overview

The Littelfuse Q8010LH5TP is a bidirectional triac belonging to the Teccor Qxx10xx series, designed for AC power control applications. It features an RMS on-state current of 10 A and supports rated repetitive peak off-state voltages up to 800 V. The device utilizes a TO-220AB package with a leaded configuration, ensuring robust thermal dissipation capabilities. Key electrical parameters include a maximum holding current of 50 mA and a gate trigger current of 50 mA. The component operates within a temperature range from -40°C to +125°C, providing reliable performance in industrial and consumer environments requiring high-voltage switching.

Triacs Feature Summary

• Bidirectional conduction capability for AC load control
• High voltage blocking rating suitable for mains applications
• Leaded TO-220AB package for efficient heat sinking

Triacs Applications

• AC motor speed control circuits
• Solid-state relay (SSR) output stages
• Lighting dimmer switches

Triacs Procurement Notes

Verify the specific suffix 'H' against official Littelfuse documentation to confirm if it denotes a specific mechanical variant or packaging option distinct from standard Q8010 models. Ensure compatibility with existing PCB footprints and thermal management designs before finalizing procurement orders.

Triacs Selection Notes

Select this component when a 10 A RMS current rating and 800 V blocking voltage are required for AC switching. The TO-220AB package is appropriate for applications necessitating direct mounting to heatsinks. Compare gate trigger characteristics with driver circuit capabilities to ensure reliable turn-on under varying temperature conditions.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx10xx family of triacs, which are widely used in general-purpose AC power control. The Q8010 designation indicates a 10 A current class within this series, sharing common design principles with other variants like the Q8010L5TP but potentially differing in specific mechanical or testing attributes defined by the manufacturer.

Triacs Replacement Considerations

Direct substitutes may include other 10 A, 800 V bidirectional triacs in TO-220 packages from manufacturers such as STMicroelectronics or Vishay. Verify pinout compatibility and thermal resistance values before substitution.
