Get the Hi-Com advantage

3Q Hi-Com Triacs are full cycle AC conduction power switches with gate triggering in three quadrants only. Their 3Q technology improves noise immunity as well as immunity to false turn-on by dV/dt. They offer high voltage and high commutation capability without the need for protection components like RC snubbers. Their wide range of gate sensitivities balances ease of triggering 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 many packages including TO-92, TO-220 and SOT186A. Surface mount options include SOT223, DPAK and D²PAK.

Superior commutation performance

Based on our planar wafer technology, our 3Q triacs provide best-in-class reliability and quality. They provide superior commutation performance, which minimizes the risk of false triggering with complex loads and in the presence of electrical noise and shocks.

Wide range

Optimized for demanding White Goods applications, our 3Q triacs offer many benefits including reduced component count, simplified circuit design and better noise immunity thanks to their improved false trigger immunity. We also offer a large variety of gate sensitivity and load current options to enable our customers to choose the right device for any application.
