How do you determine where the “load lines” will be and calculate their positions on SOA charts?


The easiest and fastest way to draw a configuration load line is to use the online Safe Operating Area (SOA) calculators available on this website. These are available on the Design Tools page under the Support header. The direct links are also provided below:

The load line for the specific product and configuration can also be created by hand using the instructions found in the particular product data sheet.
