MMBF170 from TECH PUBLIC, 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; gate-source voltage limited to ±20 V absolute maximum, with VGS(th) of 1 V min and 1.6 V typ at ID=250 µA. |
| 2 | S | passive | Source; the MOSFET source terminal, with continuous drain current of 0.3 A at TA=25°C and body diode forward current up to 0.3 A. |
| 3 | D | passive | Drain; drain-source voltage rated 60 V maximum, with continuous drain current of 0.3 A at TA=25°C and pulsed 1.5 A. |
