Abstract :
A protection system has been developed for power transistors that allows use of their full capabilities as manufactured, rather than those established by a hypothetical safe-area curve. As a result, higher power ratings can be guaranteed with a given die size. At the same time, reliability is improved by controlling peak temperature and by permitting individual devices to be 100% tested for rated power.
