BSS123-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 | G | input | Gate; voltage-controlled input with a maximum gate-source voltage of ±20 V and a gate threshold of 1.0 V min to 2.8 V max at ID=250 µA. |
| 2 | S | passive | Source terminal of the N-channel MOSFET; the body diode forward voltage is 1.3 V max at IS=0.34 A. |
| 3 | D | passive | Drain; rated for 100 V drain-source voltage and 0.17 A continuous (0.68 A pulsed) drain current. |
