SMBJ12CA-TP

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

SMBJ12CA-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 Terminal 1 passive Bi-directional TVS terminal with no polarity (SMBJ12CA: VWM 12 V, VBR 13.3-14.7 V at 1 mA, clamping 19.9 V at 30.2 A IPP); interchangeable with the other terminal.
2 Terminal 2 passive Bi-directional TVS terminal with no polarity (SMBJ12CA: VWM 12 V, VBR 13.3-14.7 V at 1 mA, clamping 19.9 V at 30.2 A IPP); interchangeable with the other terminal.

CAD (KiCad official)

  • Symbol: SMBJ12CA-TP
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: smbj12ca-tp-etched.step / smbj12ca-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smbj12ca-tp.step / smbj12ca-tp.glb are the bare package body.
