BJTs can be thought of as two diodes (P–N junctions) sharing a common region that minority carriers can move through. A PNP BJT will function like two diodes that share an N-type cathode region, and the NPN like two diodes sharing a P-type anode region. Connecting two diodes with wires will not make a BJT, since minority carriers will not be able to get from one P–N junction to the other thro… WebApr 9, 2024 · Another relationship for BJT currents we can derive is I E = (β + 1) I B.
