Default Totally Spurious Complaint


"Chris Jones"

It is easy to believe that measuring instruments with a digital display
are always right but sometimes they aren't.


** I have a few TIP35Cs in stock - Motorola and ST brands.

Connected with C and E reversed, the ST brand ones show Hfes of 20 and 26.

With correct connection, the Hfe is over 200.

This is with an Ic of 0.5 amp.

Any BJT should show a much higher Hfe with C and E used the normal way -
long as Ic is within the maker's specs.

Which does not include 2mA for a 25amp BJT.
