K210

DOWO · Schottky Diodes · SOD-123

K210 from DOWO, 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, marked by the cathode line on the package; K210 has VRRM of 100 V, IO of 2.0 A and VF of 0.85 V at IFM=2.0A.
2 A passive Anode, the end opposite the cathode line; forward current rated 2.0 A average with 40 A non-repetitive surge (IFSM).

CAD (KiCad official)

  • Symbol: K210
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: k210-etched.step / k210-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); k210.step / k210.glb are the bare package body.
