    Toshiba Released a 4500 V/1500 A Press Pack IEGT with Newly Developed Trench-Type Chips

    2 Min Read

    Toshiba Electronic Devices & Storage Corporation has launched a press pack IEGT “ST1500GXH35A” with ratings of 4500 V/1500 A that employs newly developed trench-type IEGT chips for use in high-voltage converters such as DC power transmission systems and industrial motor controllers.

    The newly developed IEGT chips reduce collector-emitter saturation-voltage and improve shutdown tolerance, short-circuit tolerance and high-temperature tolerance.

    Therefore, compared with the existing product, the collector-emitter saturation voltage (VCE(sat)) of the new ST1500GXH35A has been reduced by approximately 26 % from 3.4 V to 2.5 V (typical). In addition, the new product features wide RBSOA by improving shutdown tolerance, and tests short-circuit tolerance at a measurement voltage of 3400 V.

    Furthermore, the junction temperature rating (Tj) has been increased from 125 °C to 150 °C (maximum) by improving the high-temperature tolerance of the diode.

    ST1500GXH35A helps to reduce the size and power consumption for high-voltage converters such as DC power transmissions, static VAR compensators, and industrial motor controllers.

    Applications

    • DC power transmissions
    • Static VAR compensators
    • Industrial motor controllers

    Features

    • Low-collector-emitter saturation: VCE(sat)=2.6 V (typ.) (VGE=15 V, IC=1500 A, Tj=150 °C)
    • Expanded RBSOA (reinforced for 3400 V of test voltage), tested short-circuit tolerance
    • Maximum junction temperature rating: Tj (max)=150 °C

    Toshiba Electronic Devices & Storage Corporation has launched a newly developed press pack IEGT “ST3000GXH35A” with ratings of 4500 V/3000 A for use in high-voltage converters.

    The new product ST3000GXH35A has optimized N buffer layer design, thereby reducing approximately 400 V of turn-off-voltage oscillation peak-value (Vcp) at low current, compared with the Toshiba’s existing product. This helps simplify the snubber circuit.

    In addition, the measuring voltage of short-circuit pulse-width has been enhanced to 3400 V in response to applications requiring high voltage. This allows facilitating the short-circuit protection design of converters.

    Applications

    • DC power transmission
    • Static VAR compensator
    • Industrial motor controller

    Features

    • Maximum junction temperature rating: Tj (max)=150 °C
    • Approximately 400 V reduction in turn-off voltage oscillation peak-value (Vcp) at low current
    • Enhanced 3400 V of short-circuit pulse-width
