B540C

FUXINSEMI · Schottky Barrier Diodes (SBD) · SMC(DO-214AB)

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.

  • Symbol: B540C
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC(DO-214AB) (KiCad packages3D, STEP)
  • 3D model files: b540c-etched.step / b540c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b540c.step / b540c.glb are the bare package body.
