AU1FJ-M3/H

Overview

The AU1FJ-M3/H is a Vishay Semiconductors ultrafast recovery rectifier featuring avalanche capability. It operates with a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 1 A. The device utilizes the eSMP (SMF) surface-mount package, specifically DO-219AB-2. Key electrical characteristics include a maximum non-repetitive peak surge current of 30 A and a typical reverse leakage current of 1 uA at rated voltage. The component supports a wide operating junction temperature range from -55 °C to +175 °C.
