RB411D

Changjing · Schottky Diodes · SOT-23

RB411D from Changjing, in a SOT-23. 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 A passive Anode of the Schottky diode, per the internal diagram on page 1 (forward voltage max 0.5 V at IF=500 mA, mean rectified output current 500 mA).
2 NC unconnected No internal connection; shown as an unconnected open terminal in the page 1 diagram.
3 K passive Cathode of the Schottky diode, per the internal diagram on page 1 (DC reverse voltage 20 V, peak repetitive reverse voltage 40 V, reverse current max 30 µA at VR=10 V).

CAD (KiCad official)

  • Symbol: RB411D
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: rb411d-etched.step / rb411d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rb411d.step / rb411d.glb are the bare package body.
