KUU · MOSFETs · SOT-23
KIRLML5203TRPBF from KUU, 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 | GATE | input | Gate terminal of the P-channel MOSFET; gate-source voltage is rated at ±20 V (VGS). |
| 2 | SOURCE | passive | Source terminal; the datasheet rates continuous drain current at -3.0 A and continuous source-drain diode current at -1.3 A. |
| 3 | DRAIN | passive | Drain terminal; the datasheet rates drain-source voltage at -30 V and pulsed diode current at -24 A. |
