**BORN** · MOSFETs · SOT-23

AO3415E from BORN, 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; controls the P-channel MOSFET, with VGS limited to ±8 V and a threshold of -0.4 V min to -1.2 V max at ID=-250μA. |
| 2 | S | passive | Source; connects to the positive supply side in a high-side load switch, with continuous drain current of -4.8 A at TA=25°C. |
| 3 | D | passive | Drain; rated for VDS of -20 V, continuous current of -4.8 A at TA=25°C and pulsed current of -30 A. |
