IXYS Offers Discrete 1700V IGBT Copacks With New Soft Recovery SONIC-F

    Business Editors/High-Tech Writers

    SANTA CLARA, Calif.--(BUSINESS WIRE)--Feb. 28, 2005--IXYS Corporation (Nasdaq:SYXI) announces the availability of a new line of 1700V IGBT Copacks and Isolated Package 1700V IGBT Phase Leg Products with its proprietary 1800V SONIC-FRD(TM) ultrasoft, fast recovery diodes. These new Copack and Phase Leg products provide unique, cost effective options for customers with applications requiring 1700V power switching. IXYS is offering its fast switching "A" Version 1700V NPT IGBTs in Copack and Phase Leg configurations for PWM applications with switching frequencies up to 50kHz.
    These high voltage NPT IGBT discretes enable the elimination of more costly, lower performance solutions such as thyristors or series connected MOSFETs or IGBTs typically used at voltages above 1200V. Offered as Copacks, they offer a more complete solution for power conversion applications to improve efficiency and reliability due to reduced voltage drop, lower switching losses and the need for fewer components.
    Enhancing the efficiency and noise performance of these Copacks and Phase Legs is the use of IXYS 1800V SONIC-FRD ultrasoft, fast recovery diodes. IXYS SONIC-FRD fast and ultrafast recovery diodes are designed for temperature stability with low forward voltage and ultra-low, ultra-soft reverse recovery characteristics. In addition, IXYS SONIC-FRD diodes are optimized to provide excellent dynamic avalanche ruggedness. These diodes minimize losses in hard switching applications, while maintaining superior soft recovery characteristics to minimize switching noise and eliminate the need for costly snubber circuits.
    Copacks will be offered in 16A and 32A versions with TO-247, TO-268, PLUS247(TM) and ISOPLUS247(TM) package options. A 24A rated Phase Leg configuration is offered in IXYS proprietary ISOPLUS i4-PAC(TM). The i4-PAC is a UL recognized isolated package incorporating a DCB ceramic isolator which provides 2500Vrms isolation with superior isolated thermal performance. Two ISOPLUS i4-PAC(TM) versions are offered, including a solderable, leaded version and a surface-mountable version.
    IXYS' new 1700V discrete IGBTs provide a lower cost solution using standard PCB assembly for a broad range of high voltage applications. These high speed "A" Copacks and Phase Legs are intended for high voltage, fast switching applications such as induction heating, induction cooking, 480 to 575VAC offline inverters, flyback power supplies, UPS and microwave ovens.
