BDH8401F from Bardeen Micro, in a SOT-23-3L. 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 | VCC | power_in | Power supply pin; the datasheet gives an operating supply range of 3.8 V to 60 V and an absolute maximum VCC range of -60 V to 80 V, with reverse-supply protection built in. |
| 2 | GND | power_in | Ground pin (地) for the device. |
| 3 | VOUT | output | Open-collector output that requires an external pull-up resistor; the datasheet gives an absolute maximum VOUT of -0.5 V to 80 V and an output current of 0 to 40 mA. |
