FAST RECOVERY RECTIFIERManufacturer: Microchip Technology
Categories: Single Diodes
Quality Control: Learn More
Microchip Technology's 1N3903R is a fast-recovery rectifier designed for high-power applications. This stud-mount diode, housed in a DO-203AB (DO-5) package, offers a maximum DC reverse voltage of 400V and an average rectified current capability of 20A. Its fast recovery characteristic, with a typical reverse recovery time (trr) of 200 ns, makes it suitable for power supply rectification, high-frequency switching, and power conversion circuits. The component exhibits a forward voltage drop of 1.4V at a forward current of 63A and a low reverse leakage current of 50 µA at 400V. Operating junction temperatures range from -65°C to 150°C. This device finds application in industrial power control, automotive electronics, and telecommunications infrastructure.
