Product Introduction

Optical Semiconductor Devices
White LEDs
  • White LEDs are fabricated using the state-of-the-art gallium-nitride-on-silicon (GaN-on-Si) process that consists of a thin layer of gallium nitride grown on top of an 8-inch (200-mm) silicon wafer. They are available in LED packages suitable for various lighting applications.
Diodes
  • Rectifier Diodes
  • Schottky Barrier Diodes
Power MOSFETs
  • Medium- to high-voltage power MOSFETs: DPAK Series
    The DPAK Series incorporates a MOSFET chip fabricated using a state-of-the-art circuit design and is available in various styles of packages ranging from small D-PAK surface-mount packages to TO-220 through-hole packages. Toshiba’s power MOSFETs are available with a breakdown voltage of 250 V to 650 V and suitable for LED dimming control applications.
