Rugged, Reliable Power IGBTs

International Rectifier’s new pair of 600V 50A non-punch-through (NPT) discrete IGBTs are for motor drive applications in D2Pak and TO-220. These IGBTs feature a “square” reverse bias safe operating area (RBSOA) and 10µs short-circuit capability, which improves motor drive ruggedness and reliability. A square RBSOA means that the current rating does not degrade at higher voltage. These 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.
