All the characteristics given in this data sheet are guaranteed only with uniform
clamping force, cleaned and lubricated heatsink, surfaces with flatness < .03 mm
and roughness < 2 µm.
In the interest of product improvement ANSALDO reserves the right to change
any data given in this data sheet at any time without previous notice.
If not stated otherwise the maximum value of ratings (simbols over shaded
background) and characteristics is reported.
