MMBF170L from Slkor(SLKORMICRO Elec.), 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 with gate threshold voltage of 1 V min to 2.5 V max at VDS = 10 V, ID = 250 µA. |
| 2 | S | passive | Source terminal of the N-channel MOSFET; continuous drain current is 300 mA max. |
| 3 | D | passive | Drain terminal; drain-source voltage is 60 V max with continuous drain current of 300 mA and 800 mA pulsed (≤10 µs). |
