QJ8016LH5TP

Triacs Overview

The QJ8016LH5TP is a bidirectional triac manufactured by Littelfuse, designed for high-temperature applications. It features an RMS on-state current of 16 A and a rated repetitive off-state voltage of 800 V. The device operates within a junction temperature range up to 150°C and is housed in a TO-220AB-3 package with through-hole mounting. Key electrical parameters include a maximum holding current of 75 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 50 mA. Non-repetitive peak on-state currents are specified at 290 A and 350 A under different conditions.

Triacs Feature Summary

• High-temperature operation capability suitable for demanding thermal environments
• Standard Alternistor TRIAC design for robust switching performance
• Isolated TO-220 package configuration for secure mounting

Triacs Applications

• High-temperature industrial motor control systems
• Resistive load switching in power regulation circuits
• Solid-state relay implementations requiring high voltage isolation

Triacs Procurement Notes

Verify the specific suffix LH5TP against the manufacturer's official datasheet to confirm pinout and insulation class. Ensure the ordering quantity aligns with factory packaging standards. Cross-reference the Littelfuse part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 16 A continuous current rating are required in a TO-220 form factor. Consider the 150°C maximum junction temperature limit for thermal management calculations. Verify that the gate trigger requirements of 1.3 V and 50 mA match the driving circuit capabilities for reliable turn-on.

Triacs Part Context

This part belongs to the Qxx35xH series of high-temperature Alternistor TRIACs from Littelfuse. While similar models like the QJ8035LH5TP offer higher current ratings, the QJ8016LH5TP provides a balanced solution for moderate power applications. The series is characterized by its ability to withstand elevated operating temperatures compared to standard triacs.

Triacs Replacement Considerations

Direct substitutes may include other 800 V, 16 A TRIACs in TO-220 packages from Littelfuse or competitors. Verify equivalent electrical characteristics such as dV/dt rating and gate sensitivity. Ensure the replacement maintains the same thermal resistance and package dimensions for mechanical compatibility.
