**Infineon Technologies** · MOSFETs · TO-220AB

IRFB38N20DPBF from Infineon Technologies, in a TO-220AB. 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; controls the channel, with VGS rated at ±30 V maximum and a gate threshold of 3.0 V to 5.0 V. |
| 2 | D | passive | Drain; drain-to-source voltage is rated at 200 V, with continuous drain current of 43 A at TC = 25°C. It is also connected to the mounting tab. |
| 3 | S | passive | Source; carries the continuous source current (body diode) of 44 A maximum. |
