IRFS7440TRLPBF from Infineon Technologies, in a D2PAK. 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 of the HEXFET; gate-to-source voltage is rated at ±20 V (absolute maximum, VGS = -20 V to +20 V). |
| 2 | D | passive | Drain of the HEXFET, rated V(BR)DSS 40 V minimum and 208 A continuous drain current at TC = 25°C, limited to 120 A by the bond wire. |
| 3 | S | passive | Source of the HEXFET and body-diode cathode-side reference, with continuous body-diode source current rated at 208 A and pulsed source current at 772 A. |
