WebECE 3050 Analog Electronics - BJT Formula Summary Equations are for the npn BJT. For the pnp device, reverse the directions of all current labels and reverse the order of subscripts involving node labels, i.e. VCEbecomes VEC. When more than one equation is given, either can be used. iC= ISe vBE/VT I S= IS0 µ 1+ vCE VA ¶ iB= iC β iE= iC+iB β ... WebA bipolar junction transistor parameter similar to β is “alpha,” symbolized by the Greek letter α. It is defined as the ratio between collector current and emitter current: α = I C I E α = I C I E. Apply algebraic substitution to this formula so that alpha is defined as a function of beta: α = f (β) α = f ( β).
