SL520B

NH · Schottky Diodes · SMB

SL520B from NH, 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, identified by the white band on the package body; the SL520B is rated 200 V VRRM/VDC and 5.0 A average forward current.
2 A passive Anode, the terminal opposite the white-band cathode end; forward voltage drop is 0.85 V max at IF = 5.0 A (TA = 25℃).

CAD (KiCad official)

  • Symbol: SL520B
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: sl520b-etched.step / sl520b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sl520b.step / sl520b.glb are the bare package body.
