TWGMC · MOSFETs · SOT-23
AO3420 from TWGMC, 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 N-channel MOSFET; gate-source voltage is rated at ±12 V (VGS). |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET; continuous source current is rated at 6.5 A (IS) with pulsed source current at 14 A (ISM). |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET; drain-source voltage is rated at 20 V with continuous drain current of 6.5 A at TC=25℃. |
