  2. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    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 ...

  3. Bipolar junction transistor - Wikipedia

    en.wikipedia.org/wiki/Bipolar_junction_transistor

    BJTs PNP and NPN schematic symbols 3D model of a TO-92 package, commonly used for small bipolar transistors A bipolar junction transistor ( BJT ) is a type of transistor that uses both electrons and electron holes as charge carriers .

  4. Darlington transistor - Wikipedia

    en.wikipedia.org/wiki/Darlington_transistor

    Darlington Transistor (NPN-type) In electronics, a Darlington configuration (commonly called as a Darlington pair) is a circuit consisting of two bipolar transistors with the emitter of one transistor connected to the base of the other, such that the current amplified by the first transistor is amplified further by the second one. [1]

    Definition: A four-layer semiconductor device with a P-N-P-N structure: An insulated-gate bipolar transistor combining features from bipolar transistors and MOSFETs Terminals: Anode, cathode, gate: Emitter, collector, gate Layers: Four layers: Three layers Junction: PNPN structure: NPN(P) structure Modes of operation

  6. Diode–transistor logic - Wikipedia

    The PNP and NPN transistor symbols are those used by IBM. ... diode logic was used in the IBM 608 which was the first all-transistorized computer in the world. A ...

  7. Open collector - Wikipedia

    en.wikipedia.org/wiki/Open_collector

    The NPN BJT (n-type bipolar junction transistor) and nMOS (n-type metal oxide semiconductor field effect transistor) have greater conductance than their PNP and pMOS relatives, so may be more commonly used for these outputs. Open outputs using PNP and pMOS transistors will use the opposite internal voltage rail used by NPN and nMOS transistors.

  8. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A less common symbol is simply a series of peaks on one side of the line representing the conductor, rather than back-and-forth. Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle ...

  9. Reference designator - Wikipedia

    en.wikipedia.org/wiki/Reference_designator

    A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
