WebIn the active region, we know from the transfer characteristic curve that VBE can be approximated at 0.7 volts. We know from the output characteristic curve, that VCE is greater than 0.2 volts. We know the transistor is on, so the base current is greater than zero and we didn't obtain this equation from the characteristic curve. WebThe BJT Transfer Characteristic. This ratio is the CURRENT GAIN of the transistor and is given the symbol h fe. A fairly low gain transistor might have a current gain of 20 to 50, while a high gain type may have a gain of 300 to 800 or more. The spread of values of h fe for any given transistor is quite large, even in transistors of the same ...
