RB495D

YONGYUTAI · Schottky Diodes · SOT-23

RB495D from YONGYUTAI, 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 A1 passive Anode of the first Schottky diode, which has its cathode at pin 3; 40 V VRRM, 400 mA continuous forward current per the datasheet ratings.
2 A2 passive Anode of the second Schottky diode, which has its cathode at pin 3; 40 V VRRM, 400 mA continuous forward current per the datasheet ratings.
3 K passive Common cathode of both Schottky diodes, joined to the cathodes of the diodes on pins 1 and 2.

CAD (KiCad official)

  • Symbol: RB495D
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: rb495d-etched.step / rb495d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rb495d.step / rb495d.glb are the bare package body.
