Datasheet avalanche ratings

AN2344

18/27

To confirm that the device is working within the specification we have to check the datasheet

ratings (see Figure 14. and Figure 15.). The data is as follows:

●

T= 12

µs

●

●

●

●

●

For the peak power calculation over the conduction state, it is assumed that the worst case

and,

where,

2.4 is the derating factor found in the STP11NM60FP datasheet, in the plot showing the

Figure 13.
