Various examples are provided related to supercascode power switches that can be used in, e.g., HV and MV applications. This disclosure introduces a cascaded supercascode (CSC) power switch which can include a series of unit supercascode (USC) circuits; a control switch coupled in series with the series of USC circuits; and an external balancing network coupled to each of the n USC circuits. The series has a plurality of USC circuits, with each of the USC circuits including first and second switches coupled in series and an internal balancing network coupled across the first and second switches. A source of each of the USC circuits is a source of the first switch. The internal balancing network can include a capacitor connected between a gate of the second switch and the source of the first switch and a diode connected in parallel with the capacitor.
