Infineon SPP06N80C3 800V CoolMOS™ Power Transistor: Key Features and Applications

The Infineon SPP06N80C3 is a high-performance Power MOSFET belonging to the renowned CoolMOS™ C3 family, engineered to set new benchmarks in efficiency, power density, and reliability for switched-mode power supplies (SMPS) and other power conversion systems. This 800V superjunction MOSFET is specifically designed to meet the demanding requirements of modern electronic equipment, offering designers a superior alternative to traditional MOSFETs.

Key Features

At the core of the SPP06N80C3's advantages is its revolutionary superjunction (SJ) technology. This technology enables an exceptionally low specific on-state resistance (R DS(on)) for its voltage class, which directly translates to reduced conduction losses. When the device is switched on, it behaves like a very small resistor, minimizing power loss and heat generation.

Furthermore, this transistor exhibits outstanding switching performance. The device features low internal capacitances and an ultra-fast body diode, which collectively contribute to significantly reduced switching losses. This is crucial for high-frequency operation, allowing for the design of smaller, more compact magnetic components and filters. The combination of low R DS(on) and fast switching enables higher overall system efficiency and supports higher power density designs.

Robustness is another hallmark of this component. With a high avalanche ruggedness and an extended safe operating area (SOA), the SPP06N80C3 can handle stressful conditions, such as voltage spikes and overload scenarios, with greater margin for error, enhancing system durability and field reliability.
