RBQxx45ANZ Low IR Schottky Barrier Diodes ROHM Semiconductor RBQxx45ANZ Low IR Schottky Barrier Diodes are cathode common type diodes that come in a power mold type (TO-220FN) package. These diodes are manufactured using silicon epitaxial planar type construction. The RBQxx45ANZ barrier diodes offer low IR and high reliability. These Schottky barrier diodes are ideally suited for switching power supplies and general rectification.
