Subject: Pi Factors in 217
In 217, I noticed that there are two factors (power rating factor and voltage stress factor) in the equation of Bipolar (transistors, low freq.) , but not in Si FET (transistor, low freq.). Why? I think there are still some power and voltage effects on the failure rate of FET. Could I use the tables in Biploar to modify the equation of FET? Thanks in advance! James
