SZP6SMB33AT3G

Littelfuse · ESD And Surge Protection (TVS/ESD) · SMB

SZP6SMB33AT3G from Littelfuse, 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 Cathode passive Cathode terminal of the unidirectional TVS, identified on the package by the color band; the datasheet states the color band denotes the cathode for unidirectional components.
2 Anode passive Anode terminal of the unidirectional TVS, opposite the cathode band, which clamps transient voltages above the working peak reverse voltage (VRWM = 28.2 V for SZP6SMB33AT3G minimum breakdown, VBR 31.4 V minimum).

  • Symbol: SZP6SMB33AT3G
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: szp6smb33at3g-etched.step / szp6smb33at3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); szp6smb33at3g.step / szp6smb33at3g.glb are the bare package body.
