Infineon Technologies expands 62mm IGBT modules

Insulated gate bipolar transistors (IGBTs) have been added to the existing family of 62mm modules by Infineon Technologies.

The power modules serve the demand for higher power density without increasing package size, says Infineon. A larger chip area and an adapted direct copper bonded (DCB) substrate in the proven 62mm package are claimed to account for the performance increases. Typical applications for modules with 1200V blocking voltage are drives, solar inverters and uninterruptible power supply (UPS) as well as medium voltage drives for modules with 1700V blocking voltage.

With a blocking voltage of 1200V, the new, 62mm module reaches a maximum current rating of 600A. At 1700V blocking voltage, the maximum current rating is 500A. According to the company, this makes Infineon the market leader for this rating. The package is equipped with a base plate and its size corresponds to the industrial standard. The module can be easily be integrated into existing designs delivering, for example, 20 per cent more output power when applied for drives. The portfolio uses the IGBT4, which is a proven technology that offers high robustness and reliability, says Infineon.

Two versions of the new power modules are also available in the “common emitter” configuration, with which a three-level topology (NPC2) can be set up. This allows an efficient use in solar and UPS applications where the demand for power is high.

The new 62 mm power modules are in volume production now and are also available with pre-applied thermal interface material (TIM). Infineon also offers a new thyristor / diode modules for the input rectifier in 34mm and 50mm packages featuring solder bonding technology, to match the new 62mm modules.
