BSS138-TP from MCC Micro Commercial Components, 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 of the N-channel MOSFET; gate-source voltage is rated at ±20 V (VGS) and the threshold is 0.8 V min to 1.5 V typ at VDS=VGS, ID=1 mA. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET; drain current is rated at 0.22 A continuous with a maximum drain-source voltage of 50 V. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET; drain-source breakdown voltage is 50 V min at VGS=0 V, ID=250 µA, with total power dissipation PD of 0.35 W. |
