Hi,
I seem to get stuck on the stupidest things.
I've been reading the datasheets for two transistors, the MPSA55 and
the KSP55, and I'm curious if the polarity differences for collector
current, collector-base voltage, etc are important, because the two
transistors are "cross-referenced" on quite a few sites. The data
sheets for the transistors are located at:
http://www.fairchildsemi.com/ds/MP/MPSA55.pdf
http://www.fairchildsemi.com/ds/KS/KSP55.pdf
So for example, on the MPSA55's datasheet, Vcbo is +60V, and on the
KSP55's datasheet, Vcbo is -60V. I would like to know if the sign
difference is significant here.
I assure you that I have no intention of using these transistors any
time soon, because I know very little about them. However, they could
be useful at some point in the future, and I am trying to save myself
$6.50 from digikey by ordering them with some other stuff. So this is
officially a six dollar question. =)
Thank you very much for your help.
