It is designed for high-efficiency rectification in automotive ECUs, DC-DC converters, and reverse-polarity protection circuits where low forward voltage and fast switching are required. The 790 mV maximum forward drop at 2 A keeps conduction losses manageable in a compact SMA footprint. The 1 µA reverse leakage at 100 V matters for standby power budgets. ## Q Automotive qualification and package fit The Q Automotive series designation indicates the STPS2H100AY is qualified to AEC-Q101, the automotive stress-test qualification for discrete semiconductors. This is a prerequisite for Tier-1 automotive ECU designs and removes the need for additional qualification paperwork. It is compatible with reflow soldering and automated pick-and-place assembly. The supplier device package is SMA.","metaTitle":"STPS2H100AY Schottky Diode, 100V 2A, SMA, Q Automotive","metaDescription":"STPS2H100AY automotive Schottky rectifier: 100 V reverse voltage, 2 A average current, 790 mV Vf, -40 to 175 °C junction.
