UT3N10G-AE3-R from UTC Unisonic Tech, 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; gate-source voltage is rated ±20 V (VGSS), and VGS(TH) is 1.0 to 3.0 V at VDS = VGS, ID = 250 µA. |
| 2 | S | passive | Source terminal; the reference for the gate-source voltage ratings and the source-drain diode forward voltage (VSD 1.2 V max at IS = 1.2 A, VGS = 0 V). |
| 3 | D | passive | Drain terminal; drain-source voltage is rated 100 V (VDSS), with continuous drain current of 3.0 A at VGS = 4.5 V, TA = 25°C. |
