IXYS公司宣布,其全资子公司英国,英国Westcode IXYS有限公司推出了一个新的除了它的83毫米模相位控制晶体闸流管产品集团。

    IXYS Corporation announced that its wholly owned UK subsidiary, IXYS UK Westcode Ltd., launched a new addition to its 83mm die phase control thyristors product group. The thyristors, rated at 2200 volt, are the latest introduction to this new product group that uses an integrated die construction and improved package design for better electromechanical and thermal performances. The 2.2kV thyristor has an average current rating (Case temperature 55C) of 4340 amperes, with a junction to heat sink thermal resistance of 0.008 kelvins per watt. The new thyristor is constructed using an all diffused silicon wafer slice fused to a metal header and encapsulated in a fully hermetic package.

    This construction enhances the performance and provides excellent transient thermal and surge current ratings. – “This new addition to the product group offers exceptional current rating for this voltage class and package size, thereby maximising the power to package ratio. Older ‘alloy free’ technology is very limited in its application at lower voltage classes. This new introduction takes advantage of better silicon wafer technology and therefore reduced forward voltage drop to achieve the higher current rating and therefore higher power rating. Maximising performance through improved technology is core to IXYS’ strategy to produce the most power efficient devices,” commented Frank Wakeman, IXYS UK’s Marketing & Technical Support Manager.

    The device is available in two industry standard capsule heights and two different voltage grades. Designations are: one inch thick package N4340TJ220 (2200 Volts), N4340TJ180 (1800 Volts); one and a half inch thick package N4340TE220 (2200 Volts), N4340TE180 (1800 Volts). Additional products with voltage ratings up to 6500 volts will be launched through 2013. Typical applications for these devices include industrial drives, wind power converters, soft starters, excitation, utilities and controlled rectifiers.
