the highest expected temperature must be greater than
0.25V at 10μA, and at the lowest expected tempera-
ture, the forward voltage must be less than 0.95V at
100μA. Large power transistors must not be used. Also,
ensure that the base resistance is less than 100
. Tight
specifications for forward current gain (50 <
<150, for
example) indicate that the manufacturer has good
process controls and that the devices have consistent
V
BE
characteristics.
Manufacturers of discrete transistors do not normally
specify or guarantee ideality factor. This is normally not
a problem since good-quality discrete transistors tend
to have ideality factors that fall within a relatively narrow
range. We have observed variations in remote tempera-
ture readings of less than ±2
°
C with a variety of dis-
crete transistors. Still, it is sound design practice to
verify good consistency of temperature readings with
several discrete transistors from any manufacturer
under consideration.
