Infineon’s S5 IGBT is efficient and robust

Infineon Technologies has released the S5 IGBT range, based on the ultra-thin wafer TRENCHSTOP 5 IGBT. This range has been developed specifically for AC/DC energy conversion in industrial applications switching up to 40kHz, typically to be found in Photovoltaic Inverters or Uninterruptible Power Supplies.

The S5 device is said to feature efficiency levels up to and beyond 98% giving high energy yields for solar cell installations and reduced system costs. It is also claimed to deliver increased levels of robustness and quality to aid designers in achieving up to 20 years of operational lifetime.

The Discrete IGBT features improved switching behaviour to reduce circuit complexity and overall system costs by eliminating the need of capacitors and Zener diodes. In addition, increased robustness and quality levels are said to be enhanced further with a 25% increase in surge current handling capability. The device has a typical saturation voltage VCE(sat) of 1.60V at 175°C, meaning high efficiency can be maintained even during high temperature operations.
