  2. Silicon controlled rectifier - Wikipedia

    en.wikipedia.org/wiki/Silicon_controlled_rectifier

    A silicon-controlled switch (SCS) behaves nearly the same way as an SCR; but there are a few differences. Unlike an SCR, an SCS switches off when a positive voltage/input current is applied to another anode gate lead. Unlike an SCR, an SCS can be triggered into conduction when a negative voltage/output current is applied to that same lead.

  3. Power semiconductor device - Wikipedia

    en.wikipedia.org/wiki/Power_semiconductor_device

    Like an SCR, when a voltage pulse is present on the gate terminal, the device turns on. The main difference between an SCR and a Triac is that both the positive and negative cycle can be turned on independently of each other, using a positive or negative gate pulse. Similar to an SCR, once the device is turned on, the device cannot be turned off.

    Infrared diode: often changed to "D" for diode J: Jack (least-movable connector of a connector pair), jack connector (connector may have "male" pin contacts and/or "female" socket contacts) all types of connectors, including pin headers. JP: Jumper (link) K: Relay or contactor: L: Inductor or coil or ferrite bead: LD, LED: LED: often changed to ...

  5. Metal electrode leadless face - Wikipedia

    en.wikipedia.org/wiki/Metal_electrode_leadless_face

    Zener diode for high-reliability applications in QuadroMELF package. Because of their cylindrical shape and small size, these components can roll off the workbench or circuit board before they have been soldered into place. As such, there is a joke which suggests an alternate meaning for the acronym: Most End up Lying on the Floor. They are ...

  6. Active rectification - Wikipedia

    en.wikipedia.org/wiki/Active_rectification

    Using these ideal diodes rather than standard diodes for solar electric panel bypass, reverse-battery protection, or bridge rectifiers reduces the amount of power dissipated in the diodes, improving efficiency and reducing the size of the circuit board and the weight of the heat sink required to deal with the power dissipation.

  7. Diode modelling - Wikipedia

    en.wikipedia.org/wiki/Diode_modelling

    The Shockley diode equation relates the diode current of a p-n junction diode to the diode voltage .This relationship is the diode I-V characteristic: = (), where is the saturation current or scale current of the diode (the magnitude of the current that flows for negative in excess of a few , typically 10 −12 A).

  8. Envelope detector - Wikipedia

    en.wikipedia.org/wiki/Envelope_detector

    Between the circuit's input and output is a diode that performs half-wave rectification, allowing substantial current flow only when the input voltage is around a diode drop higher than the output terminal. The output is connected to a capacitor of value and resistor of value in parallel to ground. The capacitor is charged as the input voltage ...

  9. Diode-connected transistor - Wikipedia

    en.wikipedia.org/wiki/Diode-connected_transistor

    A diode-connected transistor is a method of creating a two-terminal rectifying device (a diode) out of a three-terminal transistor. A characteristic of diode-connected transistors is that they are always in the saturation region for metal–oxide–semiconductor field-effect transistors (MOSFETs) and junction-gate field-effect transistors ...
