BSS138BKW-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 terminal of the N-channel MOSFET; gate-source voltage is rated ±20 V per the datasheet maximum ratings. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET, the reference for the gate-source (±20 V) and drain-source (50 V) ratings. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET; drain-source voltage is rated 50 V, with continuous drain current of 0.37 A and pulsed drain current of 1.48 A listed in the ratings table. |
