Infineon launches CoolSiC MOSFET 750 V G2 with ultra-low on-resistance for automotive and industrial power electronics applications

Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) introduces the new CoolSiC MOSFET 750 V G2, which is designed to increase system efficiency and power density in automotive and industrial power conversion applications. It is available in a range of refined portfolios with R DS(on) values from 4 to 60 mΩ at 25°C and is widely used in applications such as on-board chargers (OBCs), DC-DC converters, and auxiliary equipment for electric vehicles (xEVs), as well as in industrial applications such as electric vehicle charging, photovoltaic inverters, energy storage systems, communications, and switching-mode power supplies (SMPS).

With ultra-low on-resistance of 4 mΩ and 7 mΩ, the MOSFETs excel in static switching applications and are ideal for applications such as eFuse, high-voltage battery shutdown switches, solid-state circuit breakers and solid-state relays. Infineon's innovative Q-DPAK top-sink package is designed to provide leading thermal performance and reliability, with R DS(on) values as low as 4 mΩ, achieving the best specification in the industry.

The technology also features leading R DS(on) x Q OSS and improved R DS(on) x Q fr, which reduces switching losses in both hard- and soft-switching topologies, with particularly good efficiency in hard-switching scenarios. With reduced gate charge, the technology enables faster switching speeds and lower gate drive losses, improving efficiency in high frequency applications.

In addition, the CoolSiC MOSFET 750 V G2 has a high voltage threshold (V GS(th), typ 4.5 V) at 25°C and an ultra-low Q GD/Q GS ratio, which further improves immunity to parasitic turn-on (PTO). The technology also supports extended gate drive capability to withstand static gate voltages of up to -7 V and transient gate voltages of up to -11 V. This higher voltage tolerance allows the device to be used in a wide range of applications. This increased voltage tolerance provides engineers with greater design latitude and ensures greater compatibility with other products on the market.

The CoolSiC 750 V G2 offers excellent switching performance, great ease of use, excellent reliability, and is fully compliant with AEC Q101 automotive grade parts standards and JEDEC industrial grade parts standards. The technology meets the growing market demand by enabling more efficient, compact and cost-effective designs, demonstrating Infineon's investment in reliability and durability for safety-critical automotive applications.
