VBsemi Elec · MOSFETs · TO-220F
AOTF409-VB from VBsemi Elec, in a TO-220F. 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; the datasheet limits gate-source voltage to ±20 V (VGS). |
| 2 | D | passive | Drain terminal; the datasheet rates drain-source voltage at -60 V and continuous drain current at -30 A at TC = 25 °C. |
| 3 | S | passive | Source terminal; the datasheet gives source-side ratings only through the body diode, with continuous current IS of -36 A at TC = 25 °C. |
