STPS1150A

STMicroelectronics · Schottky Barrier Diodes (SBD) · SMA

STPS1150A from STMicroelectronics, in a SMA. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode of the 150 V, 1 A Schottky rectifier (marked K in the SMA package drawing); the datasheet states VRRM of 150 V.
2 A passive Anode of the 150 V, 1 A Schottky rectifier (marked A in the SMA package drawing); the datasheet states IF(AV) of 1 A at TL = 150 °C.
