3Q Hi-Com Triacs are full cycle AC conduction power switches having gate triggering in three quadrants only. Their 3Q technology improves noise immunity as well as immunity to false turn-on by dV/dt. Their high voltage capability and range of gate sensitivities balance high commutation capability with maximum false trigger immunity. Their planar passivated construction ensures voltage ruggedness and reliability. They are pin compatible with standard 4Q triacs.

Package availability

The product family is available in a lot of power packages including SOT54, SOT78, SOT186A and many surface-mounted choices including SOT223, SOT428 & SOT404.

Superior commutation performance

Based on our planar wafer technology, our 3Q triacs provide best-in-class reliability and quality. Our 3Q triacs also provide superior commutation performance which helps our customers to minimize the risk of false triggering due to electrical noises and shocks.

Wide range

Designed mainly for the demanding whitegoods application, our 3Q triacs can benefit our customers from a lot of areas, including reduced component counts, simplified circuit design as well as better noise immunity thanks to the improved commutation performance. We also offer a large variety of gate sensivity and load current capability to enable our customers to choose the right device for any specific applications.
