International Rectifier, IR ® (NYSE: IRF), a world leader in power management technology, today announced the expansion of its portfolio of insulated-gate bipolar transistors (IGBTs) with the introduction of a family of rugged, reliable 650V devices optimized for fast switching applications including solar inverters, welding equipment, industrial motors, induction heating and uninterruptible power supplies (UPS).

Ranging from 15A to 90A, the IRGP47xx family of IGBTs utilizes trench thin-wafer technology to reduce conduction and switching losses to deliver increased system efficiency. Available as discrete devices or co-packaged with a soft recovery low Qrr diode, the new IGBTs are optimized for ultra-fast switching (8KHz-30KHz), offering an increased short circuit rating of 6µs, and positive VCE (ON) temperature coefficient for easy paralleling. The higher breakdown voltage provides extra reliability during extreme weather variations and AC-line instability, and eliminates the requirement for voltage suppression devices.

“Featuring ultra-fast switching frequency and low conduction and switching losses, the new 650V IRGP47xx family offers a cost-effective solution for applications that require a high level of efficiency, ruggedness and reliability in a smaller footprint,” said Llewellyn Vaughan-Edmunds, IGBT Product Marketing Manager, IR’s Energy Saving Products Business Unit.

Suitable for a wide range of switching frequencies, the IRGP47xx family features low V CE(ON) of 1.7V (typical) at 100°C and low total switching energy (E TS) to reduce power dissipation. Offered as packaged devices, other key features include maximum junction temperature of 175°C and low EMI for improved reliability.
