SZP6SMB200AT3G

Littelfuse · TVS · SMB

SZP6SMB200AT3G 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 of the unidirectional TVS diode, marked by the color band on the package, connected to the protected positive line (VRWM 171 V for this 200A part).
2 Anode passive Anode of the unidirectional TVS diode, connected to ground/return, with forward voltage VF of 3.5 V max at IF = 30 A.

CAD (KiCad official)

  • Symbol: SZP6SMB200AT3G
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: szp6smb200at3g-etched.step / szp6smb200at3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); szp6smb200at3g.step / szp6smb200at3g.glb are the bare package body.
