SMB3Z10A

XCH(旭昌辉) · IC · SMB

SMB3Z10A from XCH(旭昌辉), 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 K passive Cathode terminal, the end marked by the color band; it is positive relative to the anode in Zener (reverse) operation, with a nominal Zener voltage of 10.0 V (9.50 to 10.50 V) for SMB3Z10A.
2 A passive Anode terminal, the end without the color band; it is the forward-conduction anode, and maximum forward voltage is 1.2 V at 200 mA.

CAD (KiCad official)

  • Symbol: SMB3Z10A
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: smb3z10a-etched.step / smb3z10a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smb3z10a.step / smb3z10a.glb are the bare package body.
