Abstract
A packaged unidirectional power transistor comprises a package with a number of pins which provide a voltage and/or current connection between the outside and the inside. Inside the package, a bidirectional vertical power transistor is present with a controllable bidirectional current path, through a body of the bidirectional vertical power transistor, between a first current terminal of the bidirectional vertical power transistor connected to the first current pin and a second current terminal of the bidirectional vertical power transistor connected to the second current pin. A control circuit connects the control pin to the body terminal and the control terminal to drive the body and the control terminal, which allows current through the body in a forward direction, from the first current terminal to the second terminal, as a function of the control voltage, and to block current in a reverse direction regardless of the voltage.
