STPS1150 from STMicroelectronics, in a DO-41. 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, marked by the band on the DO-41 body; the 150 V (VRRM) Schottky rectifier conducts 1 A average forward current from anode to cathode. |
| 2 | A | passive | Anode of the Schottky rectifier, with VF max 0.67 V at IF = 1 A and Tj = 125 °C. |
