SMBJ85CA-13-F

Diodes Incorporated · TVS · SMB

SMBJ85CA-13-F from Diodes Incorporated, 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 A1 passive Bi-directional TVS terminal (no polarity indicator) for the SMBJ85CA with 85.0V reverse standoff voltage, 94.40-108.20V breakdown at 10mA... see note, 137V max clamping at 4.4A peak pulse current.
2 A2 passive Second bi-directional TVS terminal, interchangeable with the other terminal since bi-directional devices have no polarity indicator (cathode band is for uni-directional devices only).

CAD (KiCad official)

  • Symbol: SMBJ85CA-13-F
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: smbj85ca-13-f-etched.step / smbj85ca-13-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj85ca-13-f.step / smbj85ca-13-f.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
