EL SEGUNDO, CA. May 1997 - International Rectifier (IR) has adopted a moat structure process, used in producing very stable high-voltage input diodes, to fabricate a new standard recovery rectifier with ratings of 800 to 1600 Volts. These new diode series are the first in the industry available in plastic D-PAK and TO-252AA surface mount packages for use in this popular input rectification range.

Designated the 8EWS Series, these new input diodes offer extremely robust ratings for all line input voltages (110V - 380V). Current ratings of up to 8 amps allow an application coverage range from fractional horse power motor drives and power supplies up to 1 kilowatt. Thanks in part to the moat process, 8EWS Series devices obtain outstanding blocking voltage stability at high temperatures, and thermal cycle tests show no forward voltage change or leakage current drift.

"International Rectifier is the only company offering a SMD solution in these ranges," says Ugo Robino, Director of Business Development for Input Products at IR. "Our new 8EWS Series diodes are more efficient and reliable. And by providing the best surface mount form factor in each application, we present customers with exciting solutions to their input rectification problems. With the introduction of the 8EWS Series, we no longer just supply input rectification components, we supply valuable solutions," he added.

In general, the new 8EWS Series plastic diodes can be used in any application where input rectification of the main AC voltage is required. One ideal application class includes industrial motor control for devices like compressors and blowers, pumps, and air conditioning units from 200 W to 1.5 kW. And in power supplies and UPS systems up to 3 kilowatts for devices enterprise computer systems, Telco applications and servers, and building electrical backup.

Samples of 8EWS Series devices are available now, with production runs starting in June 1997.
