STPS3045CT from STMicroelectronics, in a TO-220AB-3. 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 | A1 | passive | Anode of diode 1 of the dual center-tap Schottky rectifier (45 V VRRM, 15 A IF(AV) per diode). |
| 2 | K | passive | Common cathode of both diodes, also connected to the metal tab (45 V VRRM). |
| 3 | A2 | passive | Anode of diode 2 of the dual center-tap Schottky rectifier (45 V VRRM, 15 A IF(AV) per diode). |
