WebThe BJT has two junctions (boundaries between the n and the p regions). These junctions are similar to the junctions we saw in the diodes and thus they may be forward biased or … Webthe body diode and the parasitic bipolar junction transistor (BJT) are formed. The reverse diode is a result of P+ body diffusion into the N epi, and the BJT is formed when the N+ source contact is diffused on top. It should be remembered that the schematic is only a lumped representation.
