NSR20F40NXT5G from onsemi, in a 0603. 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 | CATHODE | passive | Cathode terminal of the Schottky barrier diode, marked by the cathode band and PIN 1 indicator on the package; device maximum ratings are 40 V reverse voltage and 2.0 A DC forward current. |
| 2 | ANODE | passive | Anode terminal of the Schottky barrier diode; the device maximum ratings are 40 V reverse voltage and 2.0 A DC forward current, with a repetitive peak forward current of 4.0 A. |
