72HFR120

Product Overview

72HFR120 is commonly associated with Vishay / International Rectifier VS-72HFR120, a 70A standard recovery rectifier diode in a DO-203AB / DO-5 stud-mount package. The device is designed for industrial rectification and power conversion applications requiring high surge current capability, rugged construction and reliable high-voltage blocking performance. With 1200V repetitive peak reverse voltage, 70A average forward current, 1.35V class forward voltage and stud cathode / stud anode version support depending on the exact ordering code, it is suitable for converters, power supplies, machine tool controls, battery chargers, industrial equipment and legacy power system repair.
