Hi Group: I've built a test fixture for matching PNP and NPN medium power driver pairs. Right now, I'm measuring Vbe at 100uA collector current based on articles I've read. My question is should I also check higher currents?
500uA, 1mA, 10mA? My thinking is 100uA won't heat the DUT and will minimize self heating. I'm assuming if the Vbe is closely matched at 100uA it will remain matched at 20mA if the temp is the same.Any suggestions? comments appreciated.
Thanks
