Q8016LH3

Triacs Overview

The Littelfuse Q8016LH3 is a bidirectional triac designed for high-voltage power control applications. It features an 800V rated repetitive off-state voltage and supports a continuous RMS on-state current of 16A. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220-2 package for through-hole mounting. Key electrical characteristics include a maximum holding current of 50mA, a gate trigger current of 20mA, and a low on-state voltage of 1.6V. The component exhibits a maximum off-state leakage current of 5µA at the rated voltage.

Triacs Feature Summary

• High voltage blocking capability suitable for demanding AC power switching environments
• Robust thermal performance with a wide operating temperature range up to 125°C
• Low conduction loss achieved through minimized on-state voltage drop

Triacs Applications

• Industrial motor speed control systems
• Solid-state relays for AC load switching
• Lighting dimmer circuits for commercial fixtures

Triacs Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm exact gate sensitivity ratings. Ensure the procurement channel provides original Littelfuse packaging to prevent counterfeit components. Cross-reference the part number with official distributor catalogs to validate RoHS compliance status prior to finalizing orders.

Triacs Selection Notes

Select this component when an 800V rating is required for mains voltage applications. Compare the 20mA gate trigger specification against driver circuit capabilities to ensure reliable turn-on. Evaluate the TO-220-2 package constraints regarding PCB space and heatsinking requirements for sustained 16A operation under ambient conditions.

Triacs Part Context

This triac belongs to the Qxx16xHx series from Littelfuse, which focuses on high-reliability thyristor solutions. The series is engineered for industrial power control where consistent performance and robust construction are critical. It serves as a core switching element in various AC power regulation modules.

Triacs Replacement Considerations

Consult Littelfuse datasheets for direct pin-compatible alternatives within the same voltage and current class. Verify that substitute parts match the 800V blocking voltage and 16A current handling capacity. Confirm identical TO-220-2 package dimensions for mechanical interchangeability.
