IRLML5203 from Guangdong Hottech, 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 rated ±20 V and a threshold of -1.0 to -2.5 V at ID = -250µA. |
| 2 | S | passive | Source; carries the continuous body-diode current of up to -1.3 A and is the reference for VGS. |
| 3 | D | passive | Drain; rated for VDS of -30 V and continuous drain current of -3.0 A at TA = 25°C (-2.4 A at 70°C). |
