An NPN transistor looks like a pair of diodes back-to-back. The base-emitter diode is forward-biased while the base-collector diode is reverse biased. Note that the collector current does not flow to the emitter through the reverse-biased base-collector diode. Instead, it flows direct to the emitter via “transistor action”.
