Abstract :
In automotive applications, the lifetime of the power transistors is limited by the number of power pulses, induced by, e.g., short-circuit or inductive clamping events. This letter presents a solution for reliability improvement of double-diffused metal-oxide-semiconductor transistors which operate under thermomechanical stresses generated during power cycling.
