SILTEL SF-TC5.0 Thermally Conductive Gap Pad

SILTEL SF-TC5.0 is an electrically insulating fiberglass reinforced silicone film pad designed with higher thermal performance than our standard SF-TC2.0 silicone pad.  A higher performance thermal conductivity is achieved through the use of thermally conductive ceramic particles filled to a specific formulation to achieve a reduction of thermal resistance during compression as well as provide excellent handling characteristics during installation.


With its fiberglass reinforced structure, SF-TC5.0 offers great mechanical stability and high cut-through resistance.

Typical Device Applications

  • MOSFET or IBGT's
  • Power Diodes
  • AC/DC Converters
  • Power Modules
  • Motor or Power Control Units
  • TO-218, TO-220, TO-247, TO-264, etc. component packages
  • Custom Power Applications
Material Delivery Formats 

  • Sheets
  • Die Cut Individuals
  • Multiple Die Cuts per Card
