BS870-7-F 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; controls the channel, with VGS(TH) 1.0 to 3.0 V and an absolute maximum VGSS of ±20 V continuous. |
| 2 | S | passive | Source terminal of the N-channel MOSFET; the current return path, with continuous drain current up to 250 mA. |
| 3 | D | passive | Drain terminal; VDSS is 60 V, continuous drain current is 250 mA and RDS(ON) is 5 Ω max at VGS = 10 V. |
