Our comprehensive range of Rectifier Diodes offers class-leading performance and reliability. Devices are available with blocking voltages from 200 V up to 6000 V. Optimized to offer low conduction losses, these devices are ideally suited to line frequency applications up to 400Hz including input rectifiers for variable speed drives, traction converters, trackside substations, welding and DC power supplies. Featuring high temperature alloyed die construction, these devices offer low thermal impedance with high overload capacity and are designed to survive even the most arduous applications. The latest additions to the IRI Rectifier Diode family are the new 38 mm and 50 mm dia die IRI Rectifier Diodes and the new 96 mm large area rectifier diodes. These new designs are constructed using low temperature sintering technology and have an improved package design for maximum power to package ratio, as well as better thermal and electromechanical performance. The Capsule type parts are available in current ratings up to 7100 A and voltage ratings up to 6000V.
