Get the SOA draft in T3sterMaster
Step1: In Evaluate Rth setting, tape in 0.01 and click “Add”, to calculate the 0.0% pulse Zth.
Step2: In structure function section, get the Rthjc value.
Step3: In Pulse Thermal Resistance diagram, to hide the Rthja, type in Rthjc value. To get the Rthjc 0.0% curve.
Step4: In SOA Plot Setting, type in the parameters of the DUT, in the “Duty cycle” column, select the 0.0% Pulse Rthjc curve.
Step5: determine the Time[s] value to “add” into Zth-JC.
Step6: set the Axes area and the SOA plot is showed.
