Q8016LH3TP

Triacs Overview

The Littelfuse Q8016LH3TP is a bidirectional triac designed for high-power switching applications. It features an 800V repetitive peak off-state voltage and a 16A RMS on-state current rating. The device operates with gate trigger currents of 20mA across all quadrants (Q1, Q2, Q3). Key electrical parameters include a maximum holding current of 50mA and a low on-state voltage of 1.6V at rated current. Leakage current in the blocking state is limited to 5µA. The component is housed in a TO-220-2 package, facilitating efficient thermal management for industrial power control systems.

Triacs Feature Summary

• High-voltage blocking capability suitable for demanding AC line applications
• Robust 16A continuous current handling for heavy loads
• Sensitive gate drive requirements enabling direct interface with logic circuits
• Low conduction loss characteristics for improved system efficiency

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• High-power lighting dimmers
• Heating element controllers

Triacs Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications. Ensure compatibility with TO-220-2 mounting hardware. Confirm RoHS compliance status through official Littelfuse documentation prior to integration into regulated assemblies.

Triacs Selection Notes

Select this component when an 800V rating exceeds standard 600V requirements. Evaluate thermal resistance capabilities relative to the expected ambient temperature. Verify that the 20mA gate sensitivity aligns with the driving circuit's output current limits. Consider the TO-220-2 footprint constraints during PCB layout design.

Triacs Part Context

This part belongs to the Qxx16xHx series from Littelfuse, representing a family of high-current triacs. The series is engineered for robust performance in industrial environments. The Q8016LH3TP specifically targets applications requiring high voltage isolation combined with significant current capacity in a standard through-hole package.

Triacs Replacement Considerations

Consult Littelfuse cross-reference guides for verified equivalents. Ensure any substitute maintains the 800V VDRM rating and 16A IT(RMS) specification. Verify pinout compatibility with the TO-220-2 configuration before implementation.
