S5B

LGE · Diodes - General Purpose · SMB

S5B from LGE, in a SMB. 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 terminal, marked by the color band on the SMB/DO-214AA body; S5B is rated 400 V VRRM and 5.0 A average forward current.
2 A passive Anode terminal, the end opposite the color band; S5B has 1.15 V maximum forward voltage at 5.0 A.

CAD (KiCad official)

  • Symbol: S5B
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: s5b-etched.step / s5b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s5b.step / s5b.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
