HITACHI | OE a7 4. Power Bipolar Transistors 4.1 Introduction This power bipolar transistor line-up contains data on the range of Hitachis discrete devices for applications in industrial, automotive, computer and consumer equipment. 4.2 Planar Process Technology Planar technology is an optimistion of the mutliexpitaxial planar process. This new technology is used to produce high voltage, very fast switching transistors with lower switching and conduction losses, ideally for professional and industrial equipment such as power supplies, power conversion and motion controls. 4.3 Product Range Table 20 : Power Switching Transistors Range Absolute Maximum Ratings Typical Electrical Characteristics Type Number VCBO VCE(sat) tr (us) Oy.
