  • Bipolar power transistor and related integrated device with clamp means of the collector voltage
    Patent number: 7528461
    Abstract: A bipolar power transistor does not include integration of a Zener diode electrically connected between the base and collector for limiting the collector voltage. The power transistor is formed in a substrate, and includes an equalization diffusion and an auxiliary diffusion forming a P-N junction along a perimeter of the substrate. An equalization conduction layer is in contact with the equalization diffusion and the auxiliary diffusion for electrically shorting the P-N junction.
    Type: Grant
    Filed: June 9, 2006
    Date of Patent: May 5, 2009
    Assignee: STMicroelectronics S.r.l.
    Inventors: Davide Patti, Sebastiano Aparo
