IXYS Introduces a New Megapower 83mm Phase Control Thyristors with Rating of 2.2kV

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.

BIEL, Switzerland--IXYS Corporation (NASDAQ:IXYS) an international power and IC semiconductor company, today 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.

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
