Q2016RH3

Triacs Overview

The Littelfuse Q2016RH3 is a high-voltage triac designed for robust power control applications. It features a 600V repetitive peak off-state voltage and a 16A on-state current rating, housed in a TO-220AB package. The device exhibits a low on-state voltage of 1.6V and a gate trigger voltage of 2.5V, ensuring efficient switching with minimal conduction losses. With a non-repetitive peak on-state current capability of 160A and an RMS on-state current of 16A, it supports demanding industrial loads. The component operates within a junction temperature range of -40°C to +125°C and includes a heat sink mounting hole for thermal management.

Triacs Procurement Notes

Verify the specific suffix RH3 against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with existing thermal design requirements given the TO-220AB form factor. Cross-reference the part number with authorized distributors to confirm availability and authenticity before finalizing procurement plans.

Triacs Selection Notes

Select this component when a 600V rating is required for AC line voltages. The 16A continuous current rating suits moderate to high-power loads. Consider the 1.6V on-state voltage for thermal calculations in enclosed environments. Verify that the gate trigger characteristics align with the driving circuit's output capabilities for reliable turn-on.

Triacs Part Context

This triac belongs to Littelfuse's Qxx16xHx series, which focuses on high-voltage thyristor solutions. The series is engineered for reliability in harsh electrical environments.
