MBR0540T3G

onsemi · Schottky Diodes · SOD-123

MBR0540T3G from onsemi, in a SOD-123. 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, marked by the cathode band; device-level ratings are VRRM 40 V and average rectified forward current IO 0.5 A at TC = 115°C.
2 ANODE passive Anode terminal; device-level limits are peak repetitive forward current IFRM 1.0 A and non-repetitive surge current IFSM 5.5 A.

CAD (KiCad official)

  • Symbol: MBR0540T3G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: mbr0540t3g-etched.step / mbr0540t3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mbr0540t3g.step / mbr0540t3g.glb are the bare package body.
