QJ8016NH4RP

Triacs Overview

The Littelfuse QJ8016NH4RP is a bidirectional triac designed for AC switching applications. It features an RMS on-state current of 16 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device exhibits a maximum on-state voltage of 1.6 V and a non-repetitive peak on-state current capability of 200 A. Gate triggering parameters include a maximum holding current of 50 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. The component operates within a temperature range of -40°C to +150°C and is housed in a TO-263AB-3 surface-mount package.

Triacs Feature Summary

• High thermal stability with a maximum junction temperature rating of 150°C
• Integrated gate control requiring low trigger voltage and current
• Robust surge handling capability with 200 A non-repetitive peak current

Triacs Applications

• AC motor speed control circuits
• Solid-state relay implementations
• Lighting dimmer modules

Triacs Procurement Notes

Verify the specific suffix NH4RP against the manufacturer datasheet to confirm pinout and electrical tolerances. Ensure the ordering quantity aligns with the factory reel packaging requirements. Confirm RoHS compliance status through official Littelfuse documentation prior to final procurement decisions.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 16 A continuous current are required in a surface-mount form factor. The high operating temperature limit of 150°C allows for reduced heatsinking compared to standard 125°C devices. Verify that the gate drive circuit can supply at least 35 mA to ensure reliable turn-on under all load conditions.

Triacs Part Context

This part belongs to the Littelfuse QJxx16xHx series of high-temperature triacs. The series is engineered for compact power control designs where space constraints and thermal management are critical. The TO-263AB-3 package provides a balance between current carrying capacity and PCB footprint efficiency.

Triacs Replacement Considerations

The Q8016NH3RP is a related variant within the same family but utilizes an SMTO-263-2 package and has different gate characteristics. Verify mechanical compatibility and electrical parameter alignment before substitution.
