QJ4016RH3TP

Triacs Overview

The Littelfuse QJ4016RH3TP is a bidirectional triac designed for AC power control applications. It features a holding current of 20 mA and a gate trigger current range of 20-20-20 mA. The device supports a repetitive peak off-state voltage of 400 V and an on-state current rating of 16 A. Key electrical parameters include a maximum off-state leakage current of 5 uA at VDRM/IDRM and a low on-state voltage of 1.6 V. It is housed in a TO-220-2 package, suitable for high-power switching tasks requiring reliable thermal management and compact form factors.

Triacs Feature Summary

• Bidirectional conduction capability for AC load control
• Low on-state voltage for improved efficiency
• Robust thermal performance via TO-220-2 packaging

Triacs Applications

• AC motor speed control circuits
• Solid-state relay (SSR) modules
• Lighting dimmer switches

Triacs Procurement Notes

Verify the exact part number against official Littelfuse documentation, as the provided model 'QJ4016RH3TP' differs from the verified 'Q4016RH3TP'. Confirm RoHS compliance and REACH SVHC status through manufacturer datasheets before integration. Ensure ordering suffixes match specific packaging requirements such as tube quantities.

Triacs Selection Notes

Select this component based on its 400V blocking voltage and 16A current handling capacity. Evaluate the TO-220-2 package for adequate heat dissipation in your design. Compare the 1.6V on-state voltage against alternative triacs to optimize power loss. Verify gate trigger sensitivity matches your drive circuit capabilities.

Triacs Part Context

This triac belongs to the Qxx16xHx series from Littelfuse, a line focused on general-purpose AC power switching. The series offers standardized electrical characteristics for industrial and consumer applications. It complements other thyristor products in the manufacturer's portfolio for comprehensive power control solutions.

Triacs Replacement Considerations

Check for direct substitutes within the Q4016 family or equivalent 400V/16A triacs from other manufacturers. Ensure pinout compatibility and thermal resistance values match the existing PCB layout when considering alternatives.
