# AO3442-VB

**VBsemi Elec** · MOSFETs · SOT-23(TO-236)

AO3442-VB from VBsemi Elec, in a SOT-23(TO-236). 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 N-channel MOSFET; the gate-source voltage is rated at ±20 V (VGS, absolute maximum). |
| 2 | S | passive | Source of the N-channel MOSFET; the source-drain body diode is rated at 2.1 A continuous (TC = 25 °C). |
| 3 | D | passive | Drain of the N-channel MOSFET; the drain-source voltage is rated at 100 V with continuous drain current of 2.0 A at TC = 25 °C. |
