  • Description

    DF271-500 is a fast recovery diode in stud design. It has a repetitive peak reverse voltage VRRM of 1000-1400 V and low static losses. Mean forward current IFAV is 500А. Industry standard design enables easy installation into existing equipment. Maximal junction temperature Tjmax is 150 °C.

    Fast recovery (high frequency) diodes are used in static energy converters and other AC and DC circuits for frequencies of 2000 Hz or more, as well as various power units requiring low reverse recovery time trr and low recovery charge Qrr. A special feature of such diodes is their high current-carrying capacity at high frequencies.

    Fast recovery diodes by Proton-Electrotex have the following features:
    ∙ high resistance to electric and thermal cycling;
    ∙ low dynamic losses;
    ∙ low values of reverse recovery time trr and reverse recovery charge;
    ∙ 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 DF271-500 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

    High power DC drives for industry and transportation, rectifiers for electrometallurgy, invertors, frequency converters for transportation, uninterruptible power sources.
