The use of field-effect transistors as switching switches has become increasingly common in the design of SMPS (Switching Mode Power Supply) and DC-DC converters.
Evaluation method: Safe operating range of single pulse UIS (Unconstrained Inductive Switching)
When the field-effect transistor enters the breakdown effect,
Generally speaking, if the voltage of Drain and Source exceeds the maximum rated voltage specified in the specifications by a slightly larger amount,
But even if this abnormal peak voltage did not trigger the component to collapse,
This pulse has such a high power, but the resulting temperature change is only 3 ℃.
