The new IGBT utilizes Infineon’s TRENCHSTOP 5 thin-film wafer technology to achieve an industry-leading efficiency rating with a blocking voltage 50V higher than previous automotive IGBTs. This technology lowers the saturation voltage (VCE(sat)) by 200mV, reduces switching losses by half, and decreases gate charge by 2.5 times compared to existing advanced technologies. The improved switching and conduction losses support lower junction and case temperatures than other technologies, thereby increasing device reliability and minimizing cooling requirements.

By using TRENCHSTOP 5 AUTO IGBTs, electric vehicle designers can achieve efficiency gains that extend driving range and reduce battery size. For HEVs, these efficiency improvements can be utilized to reduce overall fuel consumption and lower CO2 emissions. In addition, the performance of the TRENCHSTOP 5 AUTO device enables entry into MOSFET-led applications, expanding the range of suitable semiconductor-based technologies for designers.

The TRENCHSTOP 5 AUTO IGBT has a current rating of 40A or 50A and is available as a single discrete IGBT device or in a form that incorporates Infineon's ultra-high-speed "Rapid" silicon diode. In each case, depending on whether switching speed optimization or maximum efficiency is selected as the priority design criterion, two versions, H5 HighSpeed and F5 HighSpeed FAST, are available.

Examples of efficiency gains

For standard PFCs used in onboard chargers, replacing the current 'advanced' technology with the TRENCHSTOP 5 AUTO IGBT was shown to improve efficiency from 97.5% to 97.9%. For a 3.3kW charger, this value is equivalent to a reduction in power loss of 13W. Assuming a charging time of 5 hours, this results in a reduction of 30g of CO2 emissions per charging cycle.
