1Limited only by maximum temperature
2Repetitve avalanche causes additional power losses that can be calculated as PAV=EAR*f.
3Device on 40mm*40mm*1.5mm epoxy PCB FR4 with 6cm² (one layer, 70 µm thick) copper area for drain
connection. PCB is vertical without blown air.
4Soldering temperature for TO-263: 220°C, reflow
5Co(er) is a fixed capacitance that gives the same stored energy as Coss while VDS is rising from 0 to 80% VDSS.
6Co(tr) is a fixed capacitance that gives the same charging time as Coss while VDS is rising from 0 to 80% VDSS.
