Re: transistor saturation

So I'm reading up on transistor basics:

"A transistor that is full on (with R_CE = 0) is said to be
'saturated'."

Is saturated R_CE really ever 0, though? I mean, 0.000 ohms?

My DMM routinely gives 0.1 ohm readings on bare wire, for instance.

What are typical REAL values for saturated R_CE? Say, for a TIP31A or
a 2N3055?

The datasheets don't seem to give these saturated R_CE values,
interestingly enough.

Thanks,

Look harder on the data ***.
Saturation means it's at the lowest R level it can reach per that
component.
The spec's will tell you the voltage across the CE at that point.
from there you can use ohms law to find the actual R and what ever
else you need.
