For an unbiased transistor no external power supplies are connected to it.
• We have already seen the formation of a depletion region in an unbiased p-n junction diode.
As a transistia is twined of two pi) junctions, we can apply the same concept over here as well.
• Fig. shows the depletion repions formed at the 13-E and C-B junctions of an n-p-n transistor.
