BSS123_R1_00001 from PANJIT International, 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; ESD protected to 2KV HBM, with gate-source voltage limit of ±20 V and threshold of 1 V min to 2.5 V max at ID=250uA. |
| 2 | S | passive | Source terminal of the N-channel MOSFET; continuous drain current is limited to 170 mA. |
| 3 | D | passive | Drain terminal of the N-channel MOSFET; drain-source voltage rating is 100 V with 170 mA continuous and 680 mA pulsed current. |
