  • Description

    DFA233-200 is a fast recovery avalanche diode in disc design. It has a repetitive peak reverse voltage VRRM of 1300-1500 V and low static losses. Mean forward current IFAV is 200А. Industry standard design enables easy installation into existing equipment. Maximal junction temperature Tjmax is 125 °C. Diameter of the contact surface is 25 mm.

    Avalanche diodes are designed for general application in systems up to 500 Hz. Anode and cathode are flat bases. Polarity of the diode is marked by a polarity symbol on its housing. Operation principle of avalanche diodes is based on the effect of reversible breakdown of the p-n junction under reverse voltage. As soon as the voltage reaches certain value set by design each avalanche diode, current sharply rises while voltage remains the same. Main role of avalanche diodes is protection of power circuits from overvoltages.

    Fast recovery avalanche 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 DFA233-200 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

    Fast recovery avalanche diodes are designed for static converters and other AC/DC circuits operating on standard or increased frequency requiring low reverse recovery time and high surge reverse power dissipation.
