  2. Transistor tester - Wikipedia

    en.wikipedia.org/wiki/Transistor_tester

    Transistor testers have the necessary controls and switches for making the proper voltage, current and signal settings. A meter with a calibrated "good" and "bad" scale is on the front. In addition, these transistor testers are designed to check the solid-state diodes. There are also testers for checking high transistor and rectifiers.

  3. Diode - Wikipedia

    Various semiconductor diodes. Left: A four-diode bridge rectifier. Next to it is a 1N4148 signal diode. ... an electrical check valve. Schottky diode ...

  4. Load line (electronics) - Wikipedia

    en.wikipedia.org/wiki/Load_line_(electronics)

    The characteristic curve (curved line), representing the current I through the diode for any given voltage across the diode V D, is an exponential curve. The load line (diagonal line) , representing the relationship between current and voltage due to Kirchhoff's voltage law applied to the resistor and voltage source, is

  5. Transient-voltage-suppression diode - Wikipedia

    en.wikipedia.org/wiki/Transient-voltage...

    A transient-voltage-suppression diode can respond to over-voltages faster than other common over-voltage protection components such as varistors or gas discharge tubes. The actual clamping occurs in roughly one picosecond , but in a practical circuit the inductance of the wires leading to the device imposes a higher limit.

  6. Position sensitive device - Wikipedia

    en.wikipedia.org/wiki/Position_sensitive_device

    A 2-D tetra-lateral PSD is capable of providing continuous position measurement of the incident light spot in 2-D. It consists of a single square PIN diode with a resistive layer. When there is an incident light on the active area of the sensor, photocurrents are generated and collected from four electrodes placed along each side of the square ...

  7. List of LED failure modes - Wikipedia

    en.wikipedia.org/wiki/List_of_LED_failure_modes

    Reverse bias: Although the LED is based on a diode junction and is nominally a rectifier, the reverse-breakdown mode for some types can occur at very low voltages and essentially any excess reverse bias can cause immediate degradation, and may lead to vastly accelerated failure. 5 V is a typical maximum reverse bias voltage specification for ...

  9. Diode logic - Wikipedia

    en.wikipedia.org/wiki/Diode_logic

    Diode circuit implementing AND in active-high logic. Note: in analog implementation exact output currents will be different from +5V supply. This circuit mirrors the previous gate: the diodes are reversed so that each input connects to the cathode of a diode and all anodes are connected together to the output, which has a pull-up resistor.
