Abstract
A switch device includes: a first power transistor die including a normally-on power transistor; a second power transistor die including a normally-off power transistor having a drain electrically connected to a source of the normally-on power transistor to form a cascode device; and a capacitor electrically connected between a gate of the normally-on power transistor and a source of the normally-off power transistor. Both power transistors have at most half a maximum rated drain-to-source voltage as the switch device. The second power transistor die further includes a voltage clamp circuit having a normally-off clamp transistor with a drain electrically connected to the gate of the normally-on power transistor and a source electrically connected to the source of the normally-off power transistor, and diode(s) between the drain and a gate of the normally-off clamp transistor. Additional switch devices embodiments are described.
