B540C from FUXINSEMI, in a SMC(DO-214AB). 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 of the B540C Schottky rectifier, marked by the color band on the package; the datasheet's B540C column rates it at 40 V VRRM and 5.0 A average forward current (I(AV)). |
| 2 | anode | passive | Anode of the B540C Schottky rectifier; the datasheet's B540C column gives a maximum instantaneous forward voltage of 0.55 V at 5.0 A and a maximum DC reverse current of 0.1 mA at 25°C. |
