EL SEGUNDO, Calif. October 2003 - International Rectifier, IR® (NYSE: IRF) today introduces a pair of 600V 50A non-punch-through (NPT) discrete IGBTs for motor drive applications in D2Pak and TO-220. These IGBTs feature a "square" reverse bias safe operating area (RBSOA) and 10microseconds short-circuit capability, which improves motor drive ruggedness and reliability. A square RBSOA means that the current rating does not degrade at higher voltage. IR's new IGBTs are ideal for hard-starting motor drive applications with high in-rush currents up to 6kW. Typical applications span from vacuum systems to switch reluctance (SR) drives and UPS systems.

IR's thin silicon NPT technology offers lower turn-off energy losses, allowing operation at high frequencies without any increase in conduction losses and reduced thermal resistance. The new devices can operate up to 175°C junction temperature, achieving a maximum current rating of 50A.

Mor Hezi, International Rectifier marketing manager for the Consumer and Industrial Business Unit, said, "Higher frequency operation expands motor speed range and improves torque control at lower speed while reducing audible noise. Now IR's new higher current-rated IGBTs are available in smaller packages for better board layout in high performance motor drives for lower system costs."
