Abstract
A power actuator of the emitter-switched type is described, the power actuator comprising at least one high voltage bipolar transistor and a low voltage DMOS transistor connected in cascode configuration between a collector terminal of the bipolar transistor and a source terminal of the DMOS transistor and having respective control terminals. Advantageously, the power actuator further comprises at least a Zener diode, inserted between the source terminal of the DMOS transistor and the control transistor of the bipolar transistor.
