BSS138W-TP from MCC(Micro Commercial Components), 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 | GATE | input | Gate of the N-channel MOSFET, with a maximum gate-source voltage of ±20 V and a threshold of 0.8 V min to 1.50 V max at ID=1 mA. |
| 2 | SOURCE | passive | Source of the N-channel MOSFET, with a body diode to drain and a maximum continuous drain current of 0.22 A. |
| 3 | DRAIN | passive | Drain of the N-channel MOSFET, with a maximum drain-source voltage of 50 V and a maximum RDS(on) of 3.5 ohm at VGS=10 V, ID=0.22 A. |
