Triacs datasheet and documents for QJ4016NH3RP

QJ4016NH3RP

Triacs Overview

The QJ4016NH3RP is a Littelfuse Alternistor TRIAC rated for 400 V repetitive peak off-state voltage and 16 A RMS on-state current. It utilizes a Snubberless design with a gate trigger current of 35 mA and gate trigger voltage of 1.3 V. The device features a non-repetitive surge current capacity of 167 A, an on-state voltage of 1.6 V, and a maximum holding current of 50 mA. It operates within a junction temperature range of -40 °C to +125 °C and is housed in a TO-263 (D2PAK) surface-mount package.

Triacs Feature Summary

Snubberless operation capability eliminates the need for external RC snubber networks
High thermal performance supporting elevated junction temperatures up to 125 °C
Sensitive gate drive requiring low trigger current for efficient control

Triacs Applications

Lighting dimmer circuits
Motor speed control systems
Solid-state relay modules

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified partners. Confirm RoHS compliance status and specific tape-and-reel packaging specifications prior to ordering. Ensure storage conditions adhere to manufacturer guidelines to maintain lead integrity and prevent oxidation before soldering processes.

Triacs Selection Notes

Select this component for applications requiring robust switching without external snubbers. Compare against standard TRIACs to evaluate thermal management requirements. Consider the 16 A RMS rating and 400 V blocking voltage as primary constraints for load compatibility and circuit safety margins.

Triacs Part Context

This part belongs to the Littelfuse Alternistor family, designed for high-reliability AC power control. It replaces traditional TRIACs by integrating advanced silicon technology to reduce system complexity. The D2PAK package facilitates automated surface-mount assembly for compact industrial designs.
