Its low forward voltage of 550 mV at 1 A reduces conduction loss in rectification, freewheeling, and OR-ing diode circuits. At 1 A forward current the maximum forward voltage is 550 mV, which keeps the junction temperature rise manageable in a SOD-123 footprint without forced airflow. Reverse leakage at 40 V is specified at 40 µA — typical for a Schottky of this voltage class, but worth derating if the diode sees sustained reverse bias near the maximum rating in a hot environment.","metaTitle":"STPS140ZY Schottky Diode, 40 V, 1 A, AEC-Q101, SOD-123","metaDescription":"STPS140ZY Schottky rectifier: 40 V reverse voltage, 1 A average current, 550 mV forward drop at 1 A.
