Welcome to the Vishay/General Semiconductor Trench MOS Barrier Schottky (TMBS) training module. This module will first explain the limitations of Planar Schottky rectifiers. It will then explain the construction, operation, and advantages of the new TMBS schottky rectifiers, particularly in the 100 V to 200 V class. This module will finish with a performance comparison between TMBS and Planar Schottky rectifiers.
