BAV23CA 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 | K1 | passive | Cathode of diode 1 in the BAV23CA dual common-anode pair, rated VR 200 V, IF 225 mA, VRRM 250 V. |
| 2 | K2 | passive | Cathode of diode 2 in the BAV23CA dual common-anode pair, rated VR 200 V, IF 225 mA, VRRM 250 V. |
| 3 | A | passive | Common anode of both diodes in the BAV23CA, with Ptot 350 mW for the package. |
