Hi folks, I'm a bit inexperienced with this stuff but I'm trying to find Beta for the MJE13009...the data sheet says Hfe could be anywhere from 8 to 40 so I'm a little confused....

any help would be awesome!

Thanks

Joe

Hfe is never a single number. You could set up a small test circuit to determine for yourself. Additionally, the hfe is not even a constant and changes at different base currents.
