The SOD123-FL power discrete package is part of the FLAT series of compact surface mount packages which allow ommunication equipment to be miniaturized. The Cu clip structure of interconnect features reduces electrical resistance and enhance thermal performance compared to wire-bonded products.

SOD123FL Power DiscreteThis package may also be know as:

  • S-FLAT
  • SMF
  • STmite Flat
  • JEDEC: DO-219 AB



The FLAT packages are suitable for the application of high-efficiency diodes, in small & medium size:

  • Schottky Barrier Diodes (SBDs)
  • Rectifier Diodes
  • Zener Diodes



  • Cu connector structure to reduce inductance and resistance
  • Enhance thermal property
  • Turnkey with test and packing services
  • Green materials: Pb-free plating & halogen-free mold compound


New Developments

  • Larger/higher density leadframe strips
  • Environmentally friendly Pb-free solder paste
  • Leadframe: Bare copper
  • Die attach: Solder paste
  • Interconnect: Cu clips
  • Mold compound: Halogen free
