  • Description

    TFI543-630 is a fast impulse thyristor in disc design. It has a repetitive peak off-state and reverse voltage VDRM/VRRM 1000-1500 V. Mean on-state current ITAV 630 А. The thyristor has an industry-standard ceramic housing making it easy to integrate the device into existing equipment. The maximal junction temperature Tjmax is 125 °C.

    Fast thyristors are characterized with a very low turn-off time that sets them apart from the standard models. They are used in welding, induction heating and melting, electric transportation, AC drives, UPS, and other systems requiring short turn-on and turn-off times. The thyristors have a sealed housing isolating the functional part and the semiconductor element from mechanical impacts and environment.

    This thyristor has a disc housing with pressure contacts. Disc thyristors are notable for the possibility of two-sided cooling.

    Power thyristors from Proton-Electrotex have the following features:

    ∙ low static and dynamic losses;
    ∙ high values of VDRM, VRRM;
    ∙ extensive experience of using the devices in various industries;
    ∙ range of voltages from 100 to 6500 V and amperages from 125 to 5000 A;
    ∙ high resistance to thermal and electric cycling;
    ∙ natural or forced air cooling.

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