Abstract

A switching power device (100) is provided which comprises: a normally-ON transistor (12), a normally-OFF metal-oxide-semiconductor field-effect transistor (MOSFET) (14), the normally-OFF MOSFET (14) being connected in series to a source terminal (12S) of the normally-ON transistor (12), and a driver (16) connected to and arranged to drive a gate terminal (12G) of the normally-ON transistor (12). A switching transistor (28) can then be positioned between the source terminal (12S) of the normally-ON transistor (12) and a common connection (30) of the driver (16) to protect the switching power device (100) from deleterious over-voltage and over-current spikes.
