Its 460 mV maximum forward voltage at 1 A sets the conduction-loss floor for a low-voltage rail — every mV of Vf drop is heat that must be sunk through the small package footprint. ## Reverse leakage and thermal budget at 150 °C junction Reverse leakage is 63 µA at 40 V reverse. The recovery time is rated ≤ 500 ns at forward current > 200 mA, placing it in the fast-recovery Schottky class. This suits it for low-to-mid-frequency switching supplies and polarity-protection diodes where the reverse-recovery charge is low enough to skip a snubber in most designs. ## STmite package — layout consideration The DO-216AA (STmite) package is a proprietary low-profile surface-mount body with a single cathode tab. The land pattern differs from standard SOD-123 or SMA footprints — the STM application note for the STmite package gives the recommended copper pad and solder-paste stencil aperture. Without that pattern, the solder joint area under the tab may be undersized for the 1 A continuous rating at elevated ambient.","metaTitle":"STPS1L40M Schottky Diode, 40 V, 1 A, DO-216AA STmite","metaDescription":"STPS1L40M Schottky rectifier: 40 V reverse, 1 A forward, 460 mV Vf at 1 A, 63 µA leakage at 40 V.
