IR Expands Portfolio Of 650V Devices For Solar, UPS Applications


International Rectifier has expanded 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.

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