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 ℃.
In the exported formula (3), it can also be applied to continuous forms of pulses. Formula (3) can be modified as follows to obtain its instantaneous thermal resistance:
