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 .
Band diagram for NPN transistor at equilibrium Band diagram for NPN transistor in active mode, showing injection of electrons from emitter to base, and their overshoot into the collector. BJTs can be thought of as two diodes (p–n junctions) sharing a common region that minority carriers can move through.

Schematic diagram of a single-electron transistor Left to right: energy levels of source, island and drain in a single-electron transistor for the blocking state (upper part) and transmitting state (lower part). The SET has, like the FET, three electrodes: source, drain, and a gate. The main technological difference between the transistor types ...
Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...
Cross-sectional view of a MOSFET type field-effect transistor, showing source, gate and drain terminals, and insulating oxide layer. The field-effect transistor (FET) is a type of transistor that uses an electric field to control the current through a semiconductor. It comes in two types: junction FET (JFET) and metal-oxide-semiconductor FET ...
An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily forming an electronic switch. It was developed to combine high efficiency with fast switching. It was developed to combine high efficiency with fast switching.
The transistor continuously monitors V diff and adjusts its emitter voltage to equal V in minus the mostly constant V BE (approximately one diode forward voltage drop) by passing the collector current through the emitter resistor R E. As a result, the output voltage follows the input voltage variations from V BE up to V +; hence the name ...
