MS05D5UC-B

MSKSEMI · ESD Protection Devices · SOD-523

MS05D5UC-B from MSKSEMI, in a SOD-523. 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 Pin1 passive One terminal of the bidirectional ESD protection for one I/O line, with a reverse stand-off voltage (VRWM) of 5.0 V and a minimum reverse breakdown voltage (VBR) of 6.0 V at IT = 1 mA.
2 Pin2 passive The other terminal of the bidirectional ESD protection for one I/O line, with the same 5.0 V working voltage and 6.0 V minimum breakdown limits as Pin1.

CAD (KiCad official)

  • Symbol: MS05D5UC-B
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: ms05d5uc-b-etched.step / ms05d5uc-b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ms05d5uc-b.step / ms05d5uc-b.glb are the bare package body.
