PL56B

NH · Schottky Barrier Diodes (SBD) · SMB

PL56B 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 terminal, identified by the white band on the package body; the device is rated 60 V VRRM/VDC and 5.0 A average forward current.
2 A passive Anode terminal, the end opposite the white cathode band; forward voltage is 0.55 V max at IF = 5.0 A, TA = 25℃.

CAD (KiCad official)

  • Symbol: PL56B
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: pl56b-etched.step / pl56b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pl56b.step / pl56b.glb are the bare package body.
