BAS40-05W from Nexperia, in a SOT-323. 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; the datasheet gives no pin-specific limit beyond the device limiting values (VR 40 V, IF 120 mA). |
| 2 | A2 | passive | Anode of diode 2; the datasheet gives no pin-specific limit beyond the device limiting values (VR 40 V, IF 120 mA). |
| 3 | K1, K2 | passive | Common cathode shared by diode 1 and diode 2; the datasheet gives no pin-specific limit beyond the device limiting values (VR 40 V, IF 120 mA). |
