**TECH PUBLIC** · MOSFETs · SOT-323

AO7407 from TECH PUBLIC, in a SOT-323. 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 of the P-channel enhancement-mode MOSFET, with gate-source voltage rated VGS ±10 V in the absolute maximum ratings. |
| 2 | S | passive | Source of the P-channel enhancement-mode MOSFET; the datasheet gives no separate pin-level limit for this terminal. |
| 3 | D | passive | Drain of the P-channel enhancement-mode MOSFET, rated VDS -20 V with continuous drain current -2.3 A and pulsed drain current -5.0 A (tp=10µs). |
