30 V blocking, 1 A forward — the numbers that matter
The STPS130U is a Schottky rectifier from STMicroelectronics rated for a maximum reverse voltage of 30 V and an average forward current of 1 A. The forward voltage drop is 550 mV at the full 1 A load, which keeps conduction losses low in power-supply output rectification and polarity-protection circuits.
Packaged for automated assembly
The SMB footprint is a common size for 1 A-class rectifiers, so the board layout is straightforward and the part fits existing pads for similar diodes.
