Active Schottky for low-Vf rectification
The STPS160U is an active-production Schottky rectifier from STMicroelectronics, rated 60 V reverse voltage and 1 A average forward current in the SMB (DO-214AA) surface-mount package. Forward voltage is 670 mV maximum at 1 A — this low Vf keeps conduction losses down in OR-ing, reverse-polarity protection, and freewheeling circuits where the diode sits in the main current path.
Leakage and thermal budget
Reverse leakage is 4 µA at 60 V — a low figure that helps in battery-powered or high-impedance circuits, though it rises exponentially with junction temperature.
Board-fit note: SMB package
The DO-214AA (SMB) body is roughly 4.6 mm × 3.6 mm with a gull-wing leadform — the cathode band is on the body end. The solder pad footprint matches the JEDEC standard for SMB; the anode pad is the smaller of the two terminals.
