SemiLEDs MvpLED chips are metal alloy devices which are made using a patented process entailing a vertical structure. This unique approach provides superior performance at various levels.

  • Thermal benefits: The thermal benefits enable better thermal designs, light color consistency, better lifetime and reliability
  • Efficiency benefits: The vertical structure and copper alloy p-pad, enable lower forward voltages, and better current spreading that make for better overall efficiency
  • Optical benefits: The light extraction layer and the thin structure provide a directional light output with a Lambertian pattern enabling better optical coupling and maximizing usable light

SemiLEDs chips also feature:

  • Best of breed Brightness and Reliability
  • Patented structure
  • Silver epoxy die attach compatibility (140µm high p-n junction)
  • Thin chip - 145µm
  • Available with SnCu eutectic solder
  • RoHS compliant
