Description
These GBU Series of Single Phase Bridges consist
of four glass passivated silicon junction connected
as a Full Wave Bridge. These four junctions are
encapsulated by plastic molding technique. These
Bridges are mainly used in Switch Mode power
supply and in industrial and consumer equipment.
