QJ8016LH3TP

Triacs Overview

The QJ8016LH3TP is a high-performance Alternistor TRIAC from Littelfuse, rated for 800V repetitive off-state voltage and 16A RMS on-state current. It features a gate trigger current of 20mA and an on-state voltage of 1.6V. The device operates within a temperature range of -40°C to +150°C and utilizes a TO-220AB package with internal isolation.

Triacs Feature Summary

• Features internally-isolated construction for enhanced safety in high-voltage applications
• Provides high thermal stability with a maximum junction temperature of 150°C
• Delivers robust surge capability up to 200A for reliable operation under transient conditions

Triacs Applications

• High-temperature industrial motor control systems
• Solid-state relay designs requiring electrical isolation
• Power switching circuits in harsh environmental conditions

Triacs Procurement Notes

Verify the specific suffix '3' corresponds to the required gate trigger characteristics (20mA) against your circuit design requirements. Confirm that the TO-220AB package style aligns with your PCB footprint and thermal management strategy. Ensure compliance with RoHS directives if applicable to your manufacturing process.

Triacs Selection Notes

Select this component when internal isolation is mandatory for safety standards or noise immunity. Compare the 20mA gate sensitivity against other series variants like LH4TP if lower drive power is needed. Consider the 150°C junction limit for high-ambient environments where standard TRIACs might fail.

Triacs Part Context

This part belongs to the QJxx16xHx series of high-temperature Alternistors. It shares the 16A current rating with similar models but distinguishes itself through its isolated architecture and specific gate trigger parameters designed for rugged industrial use cases.

Triacs Replacement Considerations

Direct substitutes include QJ8016LH4TP for higher gate sensitivity or QJ8016NH4RP for surface mount needs. Verify pinout compatibility and thermal resistance values before swapping packages.
