YES...
there are temperature limits for all the components......
My interest here was in the shear fact that there did exist temperature measurement
circuits using diodes and transistors.....
and
for my real world application of 350 F toner transfer I'll stick to rep-rap thermistors
which more than perform well enough for my purposes.
But the diode idea intrigued me.... simple enough... for other low temp applications.

You do realize that diodes and transistors can not handle the
temperatures involved while they have power. Most Silicon transistors
can handle up to 100C which is much lower than the temperature of the
rollers.
