    Infineon Technologies AG announced the expansion of its CoolSiC 1200 V and 2000 V MOSFET module families with a new industry-standard package. The proven 62mm device is designed in half-bridge topology and is based on the recently introduced and advanced M1H silicon carbide (SiC) MOSFET technology.

    The package enables the use of SiC for mid-power applications from 250 kW – where silicon reaches the limits of power density with IGBT technology. Compared to a 62mm IGBT module, the list of applications now additionally includes solar, server, energy storage, EV charger, traction, commercial induction cooking and power conversion systems.

    The M1H technology enables a significantly wider gate voltage window, ensuring high robustness to driver and layout-induced voltage spikes at the gate without any restrictions even at high switching frequencies. In addition to that, very low switching and transmission losses minimize cooling requirements.

    Combined with a high reverse voltage, these devices meet another requirement of modern system design. By using Infineon’s CoolSiC chip technology, converter designs can be made more efficient, the nominal power per inverter can be increased and system costs can be reduced.

    With baseplate and screw connections, the package features a very rugged mechanical design optimized for highest system availability, minimum service costs and downtime losses. Outstanding reliability is achieved through high thermal cycling capability and a continuous operating temperature (T vjop) of 150°C. The symmetrical internal package design provides identical switching conditions for the upper and lower switches. Optionally, the thermal performance of the module can be further enhanced with pre-applied thermal interface material (TIM).

    The CoolSiC 62mm package MOSFETs are available in 1200 V variants of 5 mΩ/180 A, 2 mΩ/420 A and 1 mΩ/560 A. The 2000 V portfolio will include the 4 mΩ/300 A and 3 mΩ/400 A variants. The portfolio will be completed in Q1 2024 with the 1200 V/3 mΩ and 2000 V/5 mΩ variants.

    An evaluation board is available for rapid characterization of the modules (double pulse/continuous operation). For ease of use, it provides flexible adjustment of the gate voltage and gate resistors. At the same time, it can be used as a reference design for driver boards for volume production.

    As digitalization, urbanization, and the rise of electro-mobility continue to shape the rapidly evolving world, the demand for power consumption is reaching unprecedented levels. Acknowledging energy efficiency as an important concern, Infineon Technologies AG addresses these megatrends with its silicon carbide (SiC) CoolSiC™ MOSFET 650 V in TO leadless (TOLL) packaging. The new SiC MOSFETs are enhancing Infineon’s comprehensive CoolSiC portfolio and are optimized for the lowest losses, the highest reliability, and ease-of-use in applications such as SMPS for servers, telecom infrastructure as well as energy storage systems and battery formation solutions.

    The CoolSiC 650 V high-performance trench-based power SiC MOSFETs are offered in a very granular portfolio to best suit different target applications. The new family comes in a JEDEC-qualified TOLL package featuring a low parasitic inductance, allowing for higher switching frequency, reduced switching losses, good thermal management, and automated assembly. The compact form factor enables efficient and effective usage of the board space, empowering system designers to achieve exceptional power density.

    The CoolSiC MOSFETs 650 V showcase remarkable reliability even in harsh environments, making them an ideal choice for topologies with repetitive hard commutation. The inclusion of the innovative .XT interconnect technology further enhances the devices’ thermal performance by reducing the thermal resistance (R th) and thermal impedance (Z th). In addition, the new devices feature a gate threshold voltage (V GS(th)) greater than 4 V for robustness against parasitic turn-on, a robust body diode, and the strongest gate oxide (GOX) in the market resulting in extremely low FIT (failures in time) rates.

    While a cut-off voltage (V GS(off)) of 0 V is generally recommended to simplify the driving circuit (unipolar driving), the new portfolio supports a wide driving interval of V GS voltage within the range of -5 V (turn-off) to 23 V (turn-on). This ensures ease-of-use and compatibility with other SiC MOSFETs and standard MOSFET gate-driver ICs. This is paired with higher reliability, reduced system complexity, and the enablement of automated assembly, reducing system and production costs and accelerating time-to-market.
