P6SMB56CA

DOWO · ESD And Surge Protection (TVS/ESD) · SMB(DO-214AA)

P6SMB56CA from DOWO, 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 Cathode passive Terminal 1 (listed as Cathode in the pinning table); on the bidirectional CA part it is interchangeable with pin 2, with 47.8 V stand-off and 53.2-58.8 V breakdown at 1 mA.
2 Anode passive Terminal 2 (listed as Anode in the pinning table); on the bidirectional CA part it is interchangeable with pin 1, with 600 W peak pulse power on 10/1000 us.

CAD (KiCad official)

  • Symbol: P6SMB56CA
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: p6smb56ca-etched.step / p6smb56ca-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p6smb56ca.step / p6smb56ca.glb are the bare package body.
