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. Date: 11 November 2007: Source: Own work: Author: Zedh: Other versions.svg:
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 diagram shows a schematic representation of an NPN transistor connected to two voltage sources. (The same description applies to a PNP transistor with reversed directions of current flow and applied voltage.) This applied voltage causes the lower p–n junction to become forward biased, allowing a flow of electrons from the emitter into the ...
The circuit symbol is also shown. A p–n junction is a combination of two types of semiconductor materials , p-type and n-type , in a single crystal . The "n" (negative) side contains freely-moving electrons , while the "p" (positive) side contains freely-moving electron holes .
For the BJT, on an n-p-n transistor symbol, the arrow will "Not Point iN". On a p-n-p transistor symbol, the arrow "Points iN Proudly". However, this does not apply to MOSFET-based transistor symbols as the arrow is typically reversed (i.e. the arrow for the n-p-n points inside).
In this circuit, the base terminal of the transistor serves as the input, the emitter is the output, and the collector is common to both (for example, it may be tied to ground reference or a power supply rail), hence its name. The analogous field-effect transistor circuit is the common drain amplifier and the analogous tube circuit is the ...
