QJ6016LH6TP

Triacs Overview

The Littelfuse QJ6016LH6TP is a high-temperature Alternistor TRIAC designed for robust power control applications. It features a 600V rated repetitive off-state voltage and conducts a continuous RMS on-state current of 16A. The device utilizes an isolated TO-220AB package, providing electrical isolation between the terminal and the mounting surface. Key electrical characteristics include a maximum holding current of 70mA and a gate trigger current of 80mA. It operates within a temperature range from -40°C to +150°C, ensuring reliability in demanding thermal environments.

Triacs Feature Summary

• High-temperature operation capability up to 150°C for enhanced thermal resilience
• Electrically isolated TO-220AB package design for safe mounting
• Alternistor technology combining TRIAC functionality with improved switching performance

Triacs Applications

• Industrial motor speed control systems
• High-power heating element regulation
• Solid-state relay modules requiring thermal isolation

Triacs Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm the exact voltage rating and thermal grade. Ensure the procurement specification matches the required isolation class and package variant. Cross-reference the part number with official Littelfuse databases to avoid confusion with similar series components that may have different electrical ratings or packaging configurations.

Triacs Selection Notes

Select this component when high junction temperature tolerance is critical for the application environment. The isolated package allows for direct heatsink mounting without additional insulators, simplifying mechanical design. Verify that the gate drive circuit can supply the specified 80mA trigger current reliably across the full operating temperature range to ensure consistent switching behavior.

Triacs Part Context

This part belongs to the QJxx16xHx series of Alternistor TRIACs from Littelfuse. The series is characterized by its ability to operate at elevated temperatures compared to standard TRIACs. The 'QJ' prefix typically denotes specific thermal and isolation enhancements within the broader Q-series thyristor portfolio.

Triacs Replacement Considerations

Direct substitutes must match the 600V rating, 16A current capacity, and isolated TO-220AB package. Verify that any replacement maintains the same high-temperature rating and gate trigger specifications to ensure circuit compatibility.
