IRF40R207 from Infineon Technologies, in a TO-252. 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; gate-to-source voltage is rated at ±20 V maximum, with a typical threshold of 3.0 V (2.2 V min, 3.9 V max). |
| 2 | D | passive | Drain, also connected to the D-Pak tab; drain-to-source breakdown is 40 V minimum, and continuous current is 90 A silicon limited and 56 A wire-bond limited at TC = 25°C. |
| 3 | S | passive | Source; the pulsed drain current limit of 337 A (224 A limit from source bonding technology) and body-diode continuous current of 90 A flow through this pin. |
