In bjt collector current is
WebIt looks like the transistor linked will have a typical Hfe of about 25 for 200mA collector current. This would imply 16mA into the base but, on a different device, to obtain 200mA the base current required could be double that value. Hmmm I think I'd find a transistor that had a data sheet that specified max base current. Share Cite Follow WebThe BJT is - of course - voltage controlled and not current controlled. There is not one single proof for Ib controlling Ic ! In the text, it is stated that VBE=0.6 V would be required for “overcoming the 0.6 V potential barrier”. This means: A certain Ic can be observed. OK - correct. And what happens for VBE=0.7 volts? The same current?
