60 V Schottky for automotive rectification — the Vf and Tj ceiling
The VSS8D5M6HM3/H is a Vishay TMBS® Schottky diode rated for 60 V reverse voltage and 2.7 A average rectified current, housed in the SlimSMAW package. It belongs to the Automotive, AEC-Q101, eSMP® series, meaning it is qualified to the AEC-Q101 stress and reliability standard for automotive-grade semiconductors. The forward voltage is specified at 500 mV maximum at 2.5 A — this low Vf keeps conduction losses down in high-current rectification and OR-ing applications, but the trade-off is a reverse leakage of 350 µA at 60 V, typical for a Schottky barrier. The junction temperature range extends from -40°C to 175°C, covering under-hood and engine-bay thermal profiles.
