QK016LH3TP

Triacs Overview

The Littelfuse QK016LH3TP is a bidirectional triac designed for high-power AC switching applications. It features an 800V repetitive peak off-state voltage and a 16A RMS on-state current rating, making it suitable for demanding industrial loads. The device utilizes a TO-220-2 package to facilitate efficient heat dissipation. Key electrical characteristics include a low on-state voltage of 1.6V and a gate trigger current range of 20mA to 20mA. It exhibits a maximum off-state leakage current of 5µA at rated voltage. The component operates within a junction temperature range of -40°C to +125°C and is compliant with RoHS standards.

Triacs Feature Summary

• High power handling capability with 16A continuous current rating
• Robust voltage blocking performance up to 800V
• Efficient thermal management via TO-220-2 leaded package
• Low conduction losses due to reduced on-state voltage

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules for heavy loads
• AC power regulation in heating elements

Triacs Procurement Notes

Verify the specific Littelfuse datasheet for the QK016LH3TP to confirm exact pinout configurations and absolute maximum ratings before integration. Ensure that the thermal design accounts for the TO-220-2 package requirements under full load conditions. Cross-reference the manufacturer's latest documentation to validate compliance with current environmental directives and material declarations.

Triacs Selection Notes

Select this component when designing circuits requiring robust AC switching with moderate to high current demands. The 800V rating provides sufficient margin for standard industrial line voltages. Consider the thermal resistance of the mounting surface to maintain junction temperatures within safe operating limits during continuous operation cycles.
