Ultra-fast 650-V IGBTs support fast switching applications

October 16, 2014 // By Paul Buckley
International Rectifier has expanded the company's portfolio of insulated-gate bipolar transistors (IGBTs) with the introduction of a family of rugged, reliable 650 V devices optimized for fast switching applications.

The devices are ideal for applications including solar inverters, welding equipment, industrial motors, induction heating and uninterruptible power supplies (UPS).

Ranging from 15 A to 90 A, 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 (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.

Suitable for a wide range of switching frequencies, the IRGP47xx family features low VCE(ON) of 1.7 V (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.

Availability and Pricing

Pricing for the IRGP47xx begins at $1.32 in 10,000-unit quantities. Production orders are available immediately.
