RB751S40T5G

onsemi · Schottky Barrier Diodes (SBD) · SOD-523

RB751S40T5G from onsemi, in a SOD-523. 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 (polarity band side), with reverse voltage VR of 30 V and forward continuous current IF of 30 mA.
2 ANODE passive Anode of the Schottky barrier diode, with forward voltage of 0.28 V typ (0.37 V max) at IF = 1.0 mAdc.

CAD (KiCad official)

  • Symbol: RB751S40T5G
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: rb751s40t5g-etched.step / rb751s40t5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rb751s40t5g.step / rb751s40t5g.glb are the bare package body.
