BAS21H

LGE · Switching Diodes · SOD-323

BAS21H from LGE, in a SOD-323. 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 switching diode; withstands VR 250 V continuous and VRRM 250 V, with forward continuous current IF 200 mA.
2 ANODE passive Anode of the switching diode; forward voltage max 1000 mV at IF=100 mA and 1250 mV at IF=200 mA, peak forward surge current 625 mA.

CAD (KiCad official)

  • Symbol: BAS21H
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: bas21h-etched.step / bas21h-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas21h.step / bas21h.glb are the bare package body.
