Description
These IR4GBU.. 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.
