TF2123G-E5-AQ3-R from UTC Unisonic Tech, in a SOT-723. 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 | S | passive | Source terminal; typically connected to ground or bias return; provides return path for drain current. |
| 2 | D | output | Drain terminal connected to load resistor and power supply; maximum drain current 10 mA; output signal is extracted from this node. |
| 3 | G | input | Gate input terminal for signal control; gate-source cutoff voltage VGS(OFF) is -0.38 V maximum; gate-drain voltage must not exceed -20 V. |

Package_TO_SOT_SMD:SOT-723 - 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
