**TECH PUBLIC** · MOSFETs · SOT-23

TPIRLML5103TRPBF from TECH PUBLIC, 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 of the P-channel MOSFET, with a maximum gate-source voltage of ±20 V and a threshold of -1 V min, -3 V max at ID = -250 µA. |
| 2 | S | passive | Source of the P-channel MOSFET, with a continuous source-drain body diode current of -2 A max. |
| 3 | D | passive | Drain of the P-channel MOSFET, rated for a drain-source voltage of -30 V and a continuous drain current of -2 A (-10 A pulsed). |
