BSS127S-7 from Diodes Incorporated, 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 terminal of the MOSFET; gate-source voltage is rated ±20 V (VGSS) per the maximum ratings. |
| 2 | S | passive | Source terminal of the MOSFET; the device's maximum ratings are referenced to this terminal (VDSS 600 V, VGSS ±20 V). |
| 3 | D | passive | Drain terminal of the MOSFET; drain-source voltage is rated 600 V (VDSS) and continuous drain current is 70 mA at TA = +25°C (VGS = 10 V, Note 6). |
