Rugged Phase-Control Thyristors Rated To 1140 A

IXYS’s new N1075LN180 and N1140LN140 pressure-contact, phase-control thyristors offer 1075-A and 1140-A current ratings and 1800- and 1400-V voltage ratings, respectively. The 40-mm die sizes of the devices fit into the same mechanical footprint of the company’s established products. Their design includes a new silicon die with advanced thermal bonding to a metal disk, all of which is encapsulated in rugged, hermetic ceramic packages. The package includes fewer material interfaces and enhanced gate contact, along with reduced thermal resistance and improved electrical performance. Specific measurements include a 34-mm electrode diameter, 58-mm overall diameter, and 26-mm package height, thus complying with JEDEC TO200AB. Applications include soft starters, dc drives, and controlled rectifiers that require the higher reliability of a press-pack at such current and voltage ratings.
