BAT54C-HAF from ST Semtech, in a TO-236. 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 the first Schottky diode in the BAT54C dual common-cathode configuration (30 V VRRM, 200 mA IF(AV) per the datasheet ratings). |
| 2 | A2 | passive | Anode of the second Schottky diode in the BAT54C dual common-cathode configuration (30 V VRRM, 200 mA IF(AV) per the datasheet ratings). |
| 3 | K | passive | Common cathode of both Schottky diodes in the BAT54C configuration, which is the pin 3 top terminal of the TO-236 package. |
