The SOD128-FL power discrete package is part of the FLAT series of compact surface mount packages which allow communication equipment to be miniaturized. The Cu clip structure of interconnect features reduces electrical resistance and enhance thermal performance compared to wire-bonded products.

This package may also be know as:

  • M-Flat

SOD128-FL Power DiscreteApplication

  • The FLAT packages are suitable for the application of
  • high-efficiency diodes, in small & medium size:
  • Schottky Barrier Diodes (SBDs)
  • Rectifier Diodes
