  • Description

    D143-800 is a rectifying diode in disc design. It has a repetitive peak reverse voltage VRRM of 1800-2800 V and low static losses. Mean forward current IFAV is 800А. Industry standard design enables easy installation into existing equipment. Maximal junction temperature Tjmax is 175 °C. Diameter of the contact surface is 38 mm.

    Rectifying diodes are one of the most widespread types of power switches. They are designed for use in AC/DC systems up to 500 Hz in general purpose electric devices. Anode and cathode are flat bases. Polarity of the diode is marked by a polarity symbol on its housing. The devices have a sealed housing insulating the semiconductor element from environment.

    Rectifying diodes by Proton-Electrotex have the following features:
    ∙ high resistance to electric and thermal cycling;
    ∙ low static and dynamic losses;
    ∙ high reliability means minimal equipment downtime;
    ∙ optimized for industrial use.

    At the customer's request Proton-Electrotex is able to select the optimal power diode for given operation modes. It is also possible to ship ready-to-use power semiconductors in assembly with heatsinks.

    To buy the D143-800 diode, request a quotation or a technical advice, please contact the sales department by phone +7 4862 440456 or email marketing@proton-electrotex.com.

  • Applications

    Rectifying bridges, traction converters, electric drives, invertors.
