BAT46WFILM from STMicroelectronics, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Diode anode. In SOT-323 single-diode configuration one of the two side pins is the anode; forward current flows into this pin toward the cathode (VF ~0.45 V at IF = 10 mA). |
| 2 | NC | unconnected | No internal connection. SOT-323 has three physical leads but the single-diode BAT46W only uses two of them; the middle pin on the two-lead side is unbonded. |
| 3 | K | passive | Diode cathode. Reverse leakage IR ≤ 2 µA at VR = 50 V (Tj = 25 °C); rated for 100 V repetitive peak reverse voltage. |
