Electrical Ratings and Characteristics of Power Semiconductor Switching Devices

Semiconductor device characteristics and ratings are  primarily concerned with electrical and thermal properties. The thermal properties and cooling design aspects are similar for all power switching semiconductor devices. A common, unified thermal design approach is applicable since manufacturers use the concept of a semiconductor device being thermally represented by one  virtual junction. This virtual junction is considered as the point source of all losses, which comprise on-state and off-state losses as well as switch-on and switch-off losses and any control input loss.
