ElecSuper · MOSFETs · SOT-23
AO3402A-ES from ElecSuper, 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 of the N-channel MOSFET; the datasheet limits VGS to ±12 V and gives VGS(TH) of 0.6 to 1.5 V at ID = 250 µA. |
| 2 | Source | passive | Source of the N-channel MOSFET; body diode forward voltage VSD is 1.5 V typical at VGS = 0 V and IS = 3.6 A. |
| 3 | Drain | passive | Drain of the N-channel MOSFET; the datasheet rates BVDSS at 30 V with continuous ID of 4.2 A at TA = 25 °C. |
