SMB5363A

XCH(旭昌辉) · IC · SMB

SMB5363A 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, the end marked by the color band; it is positive relative to the anode in normal zener (reverse) operation, with VZ 30 V nominal (28.5 to 31.5 V) for SMB5363A.
2 A passive Anode, the end opposite the color band; maximum forward voltage is 1.2 V at IF = 200 mA.

  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: smb5363a-etched.step / smb5363a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smb5363a.step / smb5363a.glb are the bare package body.
