UMW · MOSFETs · SOT-23
AO3442A from UMW, 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 terminal of the N-channel MOSFET, with gate-source voltage rated at ±20 V (VGS) in the absolute maximum ratings. |
| 2 | S | passive | SOURCE terminal of the MOSFET, the reference for the 100 V drain-source rating (VDS) and the 1 A continuous drain current (ID at TA=25°C). |
| 3 | D | passive | DRAIN terminal of the MOSFET, rated for 100 V drain-source voltage (VDS), 1 A continuous drain current at TA=25°C and 4 A pulsed drain current (IDM). |
