1700 V-IGBT3: field stop technology with optimized trench structure $trend setting for the high power applications in industry and traction

摘要

The IGBT3 technology, which combines a specific trench cell and the field stop concept, was first introduced for devices with 1200 V blocking voltage. It is now transferred to higher blocking voltage ratings. A new series of 1700 V devices is introduced, which compared with conventional NPT (= non punch through) devices has greatly reduced static and dynamic losses and preserves the well known ruggedness of NPT devices. With this new 1700 V chip generation a new product line of modules with up to 50% higher current capability in the same housing is available.
