UT3404G-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 | Source | passive | Source terminal of the N-channel enhancement-mode MOSFET; the datasheet gives no pin-specific limit, and the device ratings apply (VDSS 30 V, VGSS ±20 V, continuous ID 5.8 A). |
| 2 | Gate | input | Gate terminal of the MOSFET, rated for a maximum gate-source voltage of ±20 V (VGSS) with a gate threshold voltage of 1 to 3 V. |
| 3 | Drain | passive | Drain terminal of the MOSFET, rated for a drain-source voltage of 30 V (VDSS) and a continuous drain current of 5.8 A. |
