Its major feature is the introduction of an automatically controlled MCT at the anode, by which the anodeshort effect is eliminated and the voltage snapback problem is solved. Furthermore, the snapback-free characteristics can be realized in novel RC-IGBT by a single cell with a width of 10 μm with more uniform current distribution.
