Early, is the variation in the effective width of the base in a bipolar junction transistor (BJT) due to a variation in the applied base-to-collector voltage. A greater reverse bias across the collector–base junction, for example, increases the collector–base depletion width , thereby decreasing the width of the charge carrier portion of ...

In a diode model two diodes are connected back-to-back to make a PNP or NPN bipolar junction transistor (BJT) equivalent. This model is theoretical and qualitative. This model is theoretical and qualitative.
Description: PNP transistor symbol with case (IEEE 315). Note: A little confusing on the BJT page, because the NPN is drawn with Collector (C) on the top, while here it is drawn on the bottom.
Figure 3: PNP version of the emitter-follower circuit, all polarities are reversed. A small voltage change on the input terminal will be replicated at the output (depending slightly on the transistor's gain and the value of the load resistance; see gain formula below). This circuit is useful because it has a large input impedance

A simple circuit diagram showing the labels of an n–p–n bipolar transistor. A transistor can use a small signal applied between one pair of its terminals to control a much larger signal at another pair of terminals, a property called gain.
