Thinner, thermally-enhanced power discrete for smaller designs

The PSMC power discrete package from Amkor is part of our FLAT series of compact surface mount packages that is thinner and thermally enhanced, allowing for miniaturization. The copper clip interconnects structure of the PSMC package reduces electrical resistance and enhances thermal performance as compared to wire-bonded products.

With both 2 and 3 lead versions available, this package is suitable for both high-efficiency diodes as well as transistors such as Schottky Barrier Diodes (SBD), rectifier and Zener diodes, Transient Voltage Suppressors (TVS) and MOSFETs. New developments include larger/higher density leadframe strips and environmentally friendly Pb-free solder paste. This package may also be known as TO277-A, SMPC or CFP15.


  • Copper connector structure to reduce inductance and resistance
  • Enhanced thermal properties
  • Full turnkey available from wafer probe through test and packing
  • Green materials: Pb-free plating and halogen-free mold compound
