ALLPOWER ShenZhen Quan Li Semiconductor · MOSFETs · SOT-89
AP4438 from ALLPOWER ShenZhen Quan Li Semiconductor, in a SOT-89. 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; gate-source voltage limited to ±12 V absolute maximum, with VGS(th) of 1 V min to 3 V max at ID=250uA. |
| 2 | D | passive | Drain; drain-source voltage rated 30 V, continuous drain current 11.8 A at TA=25°C and 40 A pulsed. |
| 3 | S | passive | Source; connects to the source of the N-channel MOSFET, with a body diode forward voltage of 1.2 V max at IS=2.1 A. |
