SMBJ18CA-TP

MCC(Micro Commercial Components) · TVS · SMB(DO-214AA)

SMBJ18CA-TP from MCC(Micro Commercial Components), in a SMB(DO-214AA). 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 Bidirectional TVS terminal 1 (no cathode band on the C-suffix type), interchangeable with the other terminal, with 18V stand-off, 20.0-22.1V breakdown at 1mA and 29.2V maximum clamping at 20.5A.
2 A2 passive Bidirectional TVS terminal 2, interchangeable with the other terminal, with 18V stand-off, 20.0-22.1V breakdown at 1mA and 29.2V maximum clamping at 20.5A.

CAD (KiCad official)

  • Symbol: SMBJ18CA-TP
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: smbj18ca-tp-etched.step / smbj18ca-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj18ca-tp.step / smbj18ca-tp.glb are the bare package body.
