  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. Iddq testing - Wikipedia

    en.wikipedia.org/wiki/Iddq_testing

    Also, increasing circuit size means a single fault will have a lower percentage effect, making it harder for the test to detect. However, Iddq is so useful that designers are taking steps to keep it working. One particular technique that helps is power gating, where the entire power supply to each block can be switched off using a low leakage ...

  4. Power MOSFET - Wikipedia

    en.wikipedia.org/wiki/Power_MOSFET

    NXP 7030AL - N-channel TrenchMOS logic level FET IRF640 Power Mosfet die. The power MOSFET is the most widely used power semiconductor device in the world. [3] As of 2010, the power MOSFET accounts for 53% of the power transistor market, ahead of the insulated-gate bipolar transistor (27%), RF power amplifier (11%) and bipolar junction transistor (9%).

  5. Curve tracer - Wikipedia

    en.wikipedia.org/wiki/Curve_tracer

    A curve tracer is a specialised piece of electronic test equipment used to analyze the characteristics of discrete electronic components, such as diodes, transistors, thyristors, and vacuum tubes. The device contains voltage and current sources that can be used to stimulate the device under test (DUT).

  6. Transistor - Wikipedia

    en.wikipedia.org/wiki/Transistor

    Transistor packages are made of glass, metal, ceramic, or plastic. The package often dictates the power rating and frequency characteristics. Power transistors have larger packages that can be clamped to heat sinks for enhanced cooling. Additionally, most power transistors have the collector or drain physically connected to the metal enclosure.

  7. Power electronics - Wikipedia

    en.wikipedia.org/wiki/Power_electronics

    Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves. In modern systems, the conversion is performed with semiconductor switching devices such as diodes, thyristors, and power transistors such as the power MOSFET and IGBT ...

  8. Transistor count - Wikipedia

    en.wikipedia.org/wiki/Transistor_count

    The transistor count is the number of transistors in an electronic device (typically on a single substrate or silicon die).It is the most common measure of integrated circuit complexity (although the majority of transistors in modern microprocessors are contained in cache memories, which consist mostly of the same memory cell circuits replicated many times).

  9. Safe operating area - Wikipedia

    en.wikipedia.org/wiki/Safe_operating_area

    For a device that makes use of the secondary breakdown effect see Avalanche transistor. Secondary breakdown is a failure mode in bipolar power transistors. In a power transistor with a large junction area, under certain conditions of current and voltage, the current concentrates in a small spot of the base-emitter junction.
