Its 500 mV maximum forward voltage at 1 A keeps conduction loss low in low-voltage rails, while the 35 µA reverse leakage at 40 V is typical for a Schottky of this voltage class — acceptable for most DC-DC output rectification and polarity-protection roles. ## Obsolete — plan for replacement or surplus ST lists the STPS1L40MF as obsolete. For new designs or volume production, evaluate a pin-compatible 40 V, 1 A Schottky in the same DO-222AA footprint — several manufacturers offer similar ratings.","metaTitle":"STPS1L40MF Schottky Diode, 40V 1A, Fast Recovery, DO-222AA","metaDescription":"STPS1L40MF Schottky rectifier: 40V reverse, 1A average, 500mV forward drop at 1A, 35µA leakage.
