**STMicroelectronics** · Schottky Diodes · TO-220

STPS40M60CT from STMicroelectronics, in a TO-220. 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 Schottky rectifier, rated 20 A average forward current per diode and 60 V VRRM. |
| 2 | K | passive | Common cathode of both diodes, also connected to the metal tab; 60 V repetitive peak reverse voltage. |
| 3 | A2 | passive | Anode of diode 2 of the dual Schottky rectifier, rated 20 A average forward current per diode and 60 V VRRM. |
