It is AEC-Q101 qualified and the junction handles up to 175°C, which makes it a candidate for under-hood DC-DC converters, alternator rectification, and reverse-battery protection where ambient temperatures exceed 125°C. ## Forward drop and leakage — the thermal budget drivers At 3 A forward current the maximum forward voltage is 760 mV, which sets the conduction loss at roughly 2.3 W at rated current. The reverse leakage at 100 V is specified at 1.5 µA — a low value that keeps standby dissipation negligible in OR-ing and reverse-polarity circuits where the diode sits across the supply rail. The flat lead design improves heat transfer to the board compared to a standard SOD-128 with gull-wing leads.","metaTitle":"STPS3H100AFY Schottky Diode, 100 V 3 A, SOD-128, AEC-Q101","metaDescription":"STPS3H100AFY automotive Schottky rectifier, 100 V reverse, 3 A forward, 175°C Tj, SOD-128 flat package.
