Abstract

A device includes a heterojunction device, a unipolar power transistor operatively connected in series with said hetero junction device; an external control terminal for driving said unipolar power transistor and said heterojunction device; and an interface unit having a plurality of interface terminals. A first interface terminal is operatively connected to an active gate region of the heterojunction device and a second interface terminal is operatively connected to said external control terminal. The heterojunction device includes a threshold voltage less than a threshold voltage of the unipolar power transistor, wherein the threshold voltage of the heterojunction device is less than a blocking voltage of the unipolar power transistor.
