**Diodes Incorporated** · Schottky Diodes · SMC(DO-214AB)

B540C-13-F from Diodes Incorporated, 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 | K | passive | Cathode terminal, identified by the cathode band or cathode notch on the package; B540C is rated for VRRM/VR of 40V and IO of 5.0A. |
| 2 | A | passive | Anode terminal at the end opposite the cathode band; B540C has VF max 0.55V at IF = 5.0A and 0.5mA max leakage at rated VR, TA = +25°C. |
