RB751V40T1G

onsemi · Schottky Diodes · SOD-323

RB751V40T1G from onsemi, in a SOD-323. 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 40 V Schottky barrier diode (VRM 40 V peak reverse, VR 30 Vdc reverse voltage, IF 30 mA continuous forward current).
2 ANODE passive Anode of the Schottky barrier diode, with typical forward voltage of 0.28 V at IF = 1 mAdc.

CAD (KiCad official)

  • Symbol: RB751V40T1G
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: rb751v40t1g-etched.step / rb751v40t1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rb751v40t1g.step / rb751v40t1g.glb are the bare package body.
