B5819W-G

Changjing · Schottky Diodes · SOD-123

B5819W-G from Changjing, 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 K passive Cathode, the lead marked with the bar (shown as "−") on the package; B5819W-class diode has VRRM 40 V and IO 1 A.
2 A passive Anode, the lead opposite the cathode bar (shown as "+") on the package; forward current up to 1 A average (IFRM 1.5 A, IFSM 9 A).

CAD (KiCad official)

  • Symbol: B5819W-G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: b5819w-g-etched.step / b5819w-g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b5819w-g.step / b5819w-g.glb are the bare package body.
