  2. Thyristor - Wikipedia

    en.wikipedia.org/wiki/Thyristor

    A thyristor (/ θaɪˈrɪstər /) is a solid-state semiconductor device which can be thought of as being a highly robust and switchable diode, allowing the passage of current in one direction but not the other, often under control of a gate electrode, that is used in high power applications like inverters and radar generators.

  3. Power semiconductor device - Wikipedia

    en.wikipedia.org/wiki/Power_semiconductor_device

    Power semiconductor device. Appearance. A power semiconductor device is a semiconductor device used as a switch or rectifier in power electronics (for example in a switch-mode power supply). Such a device is also called a power device or, when used in an integrated circuit, a power IC. A power semiconductor device is usually used in ...

  4. Integrated gate-commutated thyristor - Wikipedia

    en.wikipedia.org/wiki/Integrated_gate-commutated...

    Electronic symbol. The integrated gate-commutated thyristor (IGCT) is a power semiconductor electronic device, used for switching electric current in industrial equipment. It is related to the gate turn-off (GTO) thyristor. It was jointly developed by Mitsubishi and ABB. [1] Like the GTO thyristor, the IGCT is a fully controllable power switch ...

    A high ⁡ ⁡ between MT2 and MT1 may turn on the TRIAC when it is off. Typical values of critical static d v /d t are in the terms of volts per microsecond. The turn-on is due to a parasitic capacitive coupling of the gate terminal with the MT2 terminal, which lets currents into the gate in response to a large rate of voltage change at MT2.

    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%).

    en.wikipedia.org/wiki/Transistor

    The first high-frequency transistor was the surface-barrier germanium transistor developed by Philco in 1953, capable of operating at frequencies up to 60 MHz. [33] They were made by etching depressions into an n-type germanium base from both sides with jets of indium(III) sulfate until it was a few ten-thousandths of an inch thick.

  9. Thyratron - Wikipedia

    en.wikipedia.org/wiki/Thyratron

    Reference 2D21 tube is 2 ⅛ inches tall (54 mm). A thyratron is a type of gas-filled tube used as a high-power electrical switch and controlled rectifier. Thyratrons can handle much greater currents than similar hard-vacuum tubes. Electron multiplication occurs when the gas becomes ionized, producing a phenomenon known as a Townsend discharge.
