DESCRIPTION
The UTC BTA08A is a 8A triacs which can be operated in 3
quadrants only, it uses UTC’s advanced technology to provide
customers with high commutation performances, etc.
The UTC BTA08A 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.
