Abstract
A hybrid power MOSFET having a low blocking-capability MOSFET and a high blocking-capability junction FET is disclosed. In accordance with the present invention, this cascode circuit has at least two high blocking-capability junction FETs which are electrically connected in parallel and whose gate connections are respectively electrically conductively connected to the source connection of the low blocking-capability MOSFET by means of a connecting line. Thus, a hybrid power MOSFET for a high current-carrying capacity is obtained whose design technology has been considerably simplified on account of the use of only one control line and n+1 chips.
