PM3401B from Shandong Jingdao Microelectronics, in a SOT-23. 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 | Gate | input | Gate terminal; the datasheet rates the gate-source voltage at ±12 V (VGS). |
| 2 | Drain | passive | Drain terminal; the device is rated at a drain-source voltage of -30 V (VDS) and a continuous drain current of -4.2 A (ID). |
| 3 | Source | passive | Source terminal; the datasheet gives no source-specific limit, only the device-level ratings (VDS -30 V, operating and storage temperature -55 to +150 °C). |
