Introduction
Datasheets of the modern power MOSFET devices, either of low voltage or of high voltage,
show in the section entitled "Absolute Maximum Rating" the values of some important
parameters that regard the SOA (safe operating area). As it is well kwown in literature, SOA
is the area that includes all the ID-VDS operating points where the device works in safety
conditions.
