T820W/T830W 8A SNUBBERLESS™ TRIAC is a bidirectional thyristor produced by ST. It is specially recommended for use on inductive loads, such as washing-machines drum motor controllers.
This document is a datasheet for the STMicroelectronics T820W and T830W Snubberless TRIAC series. These components are designed with ST's Snubberless technology to provide high commutation performance, making them specifically recommended for use on inductive loads such as washing-machine drum motor controllers. The devices comply with UL standards (ref. E81734) and are available in ISOWATT220AB plastic packages.
