Developed for AC-DC energy conversion in industrial applications with switching speeds up to 40 kHz

Infineon has launched a new S5 (S for soft) product family that improves IGBT performance.

Based on ultra-thin wafer TRENCHSTOP™ 5 IGBTs, this product family has been specifically developed for AC-DC energy conversion in industrial applications switching up to 40 kHz, typically found in photovoltaic (PV) inverters or uninterruptible power supplies (UPS).

The S5 device meets manufacturers' requirements to increase system efficiency levels to over 98 percent to achieve maximum energy output from solar installations, while reducing system costs.

The products help end customers achieve an operating life of up to 20 years due to increased robustness and quality levels. IGBTs provide customers with improved efficiency, cost competitiveness and robustness throughout their systems.

The improved switching characteristics of discrete IGBTs eliminate the need for capacitors and Zener diodes, reducing circuit complexity and ultimately lowering overall system cost.

Capacitors and Zener diodes are primarily required to achieve maximum efficiency and robustness, but these can be eliminated when using TRENCHSTOP 5 S5.

Additionally, surge current handling performance has been increased by 25 percent, further enhancing robustness and quality levels, providing customers with high reliability for a robust design.

The newly released devices achieve an industry-leading low saturation voltage V _CE(sat) of 1.60 V (typical) at 175 °C, allowing them to maintain high efficiency even at high temperature operation.

The 30A, 40A, 50A and 75A current classes are available in a TO-247 3-pin package, co-packaged with the Rapid1 freewheeling diode.
