Infineon ICE5QR1680AG: A High-Performance 1600V CoolSiC™ Hybrid Discrete for Automotive and Industrial Applications
The relentless push for higher efficiency, greater power density, and improved reliability in power electronics is driving the adoption of wide-bandgap semiconductors. At the forefront of this revolution is Infineon Technologies with its latest offering, the ICE5QR1680AG, a 1600V CoolSiC™ Hybrid Discrete device engineered to set new benchmarks in both automotive and industrial sectors.
This innovative component represents a significant leap forward by merging a state-of-the-art 1600V SiC MOSFET with a tailored anti-parallel Silicon Carbide (SiC) Schottky barrier diode (SBD) in a single TO-247-3 housing. This hybrid approach is not merely a packaging exercise; it is a strategic design that leverages the inherent strengths of SiC technology. The high-voltage capability of 1600V provides a substantial safety margin and robustness, making it exceptionally suitable for demanding applications often plagued by voltage spikes and harsh electrical environments.
A key advantage of the CoolSiC™ MOSFET is its superior switching performance. Compared to traditional silicon-based IGBTs, it offers significantly lower switching losses, which directly translates into higher system efficiency. This allows for the design of power converters that can operate at higher switching frequencies. The benefit is twofold: it reduces the size and weight of passive components like magnetics and filters, leading to more compact and cost-effective systems, while also minimizing overall power loss. The integrated SiC SBD further enhances this performance by eliminating the reverse recovery charge (Qrr) typical of silicon PN diodes, thereby reducing switching noise and loss during hard commutation events.
The robustness and reliability of the ICE5QR1680AG are paramount, especially for automotive applications like ons-board chargers (OBC) and DC-DC converters in electric vehicles (EVs). These systems require components that can withstand high temperatures and operate reliably over long lifetimes. The SiC technology's ability to operate at higher junction temperatures contributes to a more resilient design. In industrial settings, this hybrid discrete is ideal for power supplies, solar inverters, and motor drives, where efficiency and durability are critical for operational cost savings and uptime.
Furthermore, by offering this as a hybrid discrete, Infineon simplifies the design-in process for engineers. It guarantees optimized matching between the MOSFET and diode, reduces parasitic inductance associated with discrete interconnections, and saves valuable PCB space, accelerating time-to-market for end products.
ICGOOODFIND: The Infineon ICE5QR1680AG is a powerhouse component that encapsulates the future of power conversion. It successfully addresses the core challenges of modern electronics by delivering a potent combination of high voltage resilience, exceptional switching efficiency, and robust integration. It is a pivotal solution enabling next-generation electric vehicles and industrial systems to achieve unprecedented levels of performance and energy savings.
