YFW1012T from YFW, in a SOT-523. 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 | GATE | input | Gate terminal of the N-channel MOSFET; gate-source voltage is rated at ±6 V (VGSS), and a gate protection diode is included in the equivalent circuit. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET; the device is rated for a 20 V drain-source voltage (VDSS) with this pin as the source reference. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET; rated for 0.63 A continuous drain current at TA = 25°C (steady state) and 6 A pulsed drain current (IDM). |
