DESCRIPTION
The UTC BTB310A is a 10A triacs which can be operated in 3
quadrants, it uses UTC’s advanced technology to provide
customers with high commutation performances.
The UTC BTB310A is suitable for inductive load switching
operations, also can be used in ON/OFF function applications such
as induction motor starting circuits, heating regulation, static relays
etc.
