Ultra-fast trench IGBTs rated 650V, for welding, solar, motors, induction heating

October 20, 2014 // By Graham Prophet
International Rectifier has added insulated-gate bipolar transistors (IGBTs) with 650V devices optimised 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 uses 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, these IGBTs are optimised for ultra-fast switching (8 kHz-30 kHz), 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.

They feature 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.
