MSESD2CAN

MSKSEMI · ESD And Surge Protection (TVS/ESD) · SOT-23

MSESD2CAN from MSKSEMI, in a SOT-23. 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 I/O1 passive Protected line 1 (TVS diode to common pin 3); working voltage 24V VRWM, 27V breakdown at 1mA, ±30kV IEC 61000-4-2 ESD.
2 I/O2 passive Protected line 2 (TVS diode to common pin 3); working voltage 24V VRWM, 27V breakdown at 1mA, ±30kV IEC 61000-4-2 ESD.
3 COMMON passive Common pin joining the two TVS diodes in the pin configuration diagram; the datasheet does not state a ground or supply role for it.

CAD (KiCad official)

  • Symbol: MSESD2CAN
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: msesd2can-etched.step / msesd2can-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); msesd2can.step / msesd2can.glb are the bare package body.
