SMFJ58A

BORN · ESD And Surge Protection (TVS/ESD) · SOD-123F

SMFJ58A from BORN, in a SOD-123F. 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 of the unidirectional TVS (marked end with the band), connected to the protected line; reverse stand-off voltage VR is 58 V and breakdown voltage is 64.4 V min to 71.2 V max at 1 mA.
2 A passive Anode of the unidirectional TVS, normally connected to ground; maximum clamping voltage is 93.6 V at 2.1 A peak pulse current.

CAD (KiCad official)

  • Symbol: SMFJ58A
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123F (KiCad packages3D, STEP)
  • 3D model files: smfj58a-etched.step / smfj58a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smfj58a.step / smfj58a.glb are the bare package body.
