QJ6016LH452TP

Triacs Overview

The QJ6016LH452TP is a high-temperature Alternistor TRIAC manufactured by Littelfuse, 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 a TO-220AB-3 isolated package for through-hole mounting, ensuring electrical isolation between the case and terminals. Key electrical characteristics include a maximum holding current of 15mA, a gate trigger current of 10mA, and an on-state voltage of 1.6V. It supports non-repetitive surge currents up to 200A and operates within a temperature range of -40°C to +150°C.

Triacs Feature Summary

• High-temperature operation capability with a maximum junction temperature rating of 150°C
• Electrically isolated TO-220AB-3 package design for enhanced safety in grounded applications
• Low gate sensitivity requiring only 10mA trigger current for reliable switching
• High surge current handling capacity suitable for inductive load commutation

Triacs Applications

• Industrial motor speed control systems
• High-temperature heating element regulation
• Solid-state relay modules requiring isolation
• Power factor correction circuits

Triacs Procurement Notes

Verify the specific suffix '452' against official Littelfuse documentation to confirm exact pinout and isolation specifications, as distributor listings may vary. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the TO-220AB-3 package variant matches the thermal management requirements of the target application. Request batch traceability data if used in safety-critical industrial equipment. Validate that the supplier is an authorized distributor to guarantee component authenticity.

Triacs Selection Notes

Select this component when high-temperature stability and electrical isolation are required in power switching designs. The 16A current rating suits moderate-power industrial loads, while the 600V blocking voltage handles standard AC line voltages. Consider the 10mA gate drive requirement for compatible control logic interfaces. The isolated package eliminates the need for additional insulating hardware, simplifying mechanical assembly compared to non-isolated alternatives.

Triacs Part Context

This part belongs to the QJxx16xHx series of high-temperature TRIACs from Littelfuse. It shares the 16A current class with other variants but distinguishes itself through the specific '452' suffix indicating the isolated TO-220AB-3 configuration. This series targets applications demanding higher thermal resilience than standard TRIACs, offering improved reliability in harsh environments where ambient temperatures exceed typical operating limits.

Triacs Replacement Considerations

QJ6016LH2TP is a documented substitute within the same manufacturer family, sharing identical electrical ratings and package type.
