S-SMDJ58A

LRC · TVS · SMC

S-SMDJ58A from LRC, in a SMC. 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, marked by the color band on the SMC (DO-214AB) body; connect to the protected line (positive side) of this unidirectional TVS.
2 A passive Anode terminal, the end without the color band on the SMC (DO-214AB) body; connect to ground/return of this unidirectional TVS.

CAD (KiCad official)

  • Symbol: S-SMDJ58A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: SMC (KiCad packages3D, STEP)
  • 3D model files: s-smdj58a-etched.step / s-smdj58a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s-smdj58a.step / s-smdj58a.glb are the bare package body.
