A schematic diagram of the Ebers-Moll models of a PNP BJT. The base, collector and emitter currents are I B, I C and I E, the common-base forward and reverse current gains are α F and α R, and the collector and emitter diode currents are I CD and I ED.

The 2N3906 is a commonly used PNP bipolar junction transistor intended for general purpose low-power amplifying or switching applications. [1] [2] It is designed for low electric current and power and medium voltage, and can operate at moderately high speeds. It is complementary to the 2N3904 NPN transistor. [3]
The w:depletion regions of the emitter-base and base-collector junctions are marked. E c {\displaystyle E_{c}} is the w:conduction band , E f {\displaystyle E_{f}} indicates the quasi- w:fermi energy levels, E i {\displaystyle E_{i}} is the intrinsic Fermi level of the undoped semiconductor, and E v {\displaystyle E_{v}} is the w:valence band .
In what is called active mode, the base–emitter voltage and collector–base voltage are positive, forward biasing the emitter–base junction and reverse-biasing the collector–base junction. In this mode, electrons are injected from the forward biased n-type emitter region into the p-type base where they diffuse as minority carriers to the ...
A bipolar junction transistor (BJT) has terminals labeled base, collector and emitter. A small current at the base terminal, flowing between the base and the emitter, can control or switch a much larger current between the collector and emitter. A field-effect transistor (FET) has terminals labeled gate, source and drain. A voltage at the gate ...

require a base-emitter voltage (V BE(on)) in the range of 0.55 to 0.7 volts for a collector current of 2 mA when the Collector voltage is 5 volts. [ 4 ] Will have a saturation voltage (V CE(sat) ) of at most 0.2 volts (typically 0.07 volts) at a collector current of 10 mA and a base current of 0.5 mA (when the base voltage is typically 0.73 ...
