Infineon SPA16N50C3: A High-Performance 500V Super Junction Power MOSFET

The relentless pursuit of higher efficiency and power density in modern power electronics drives the need for superior switching components. At the forefront of this innovation is Infineon Technologies with its SPA16N50C3, a 500V Super Junction (SJ) MOSFET engineered to set new benchmarks in performance for a wide range of power conversion applications.

Built on Infineon's advanced CoolMOS™ C3 super junction technology, the SPA16N50C3 is designed to minimize key losses that typically plague conventional MOSFETs. It achieves an outstandingly low figure-of-merit (R DS(on) x Q g), which signifies an optimal balance between low conduction losses and low switching losses. This translates directly into higher overall system efficiency and the potential for increased switching frequencies, allowing for the design of smaller, lighter magnetic components and heat sinks.

The device boasts a maximum drain-source voltage (V DS) of 500V, making it exceptionally suitable for mains-powered applications, including switched-mode power supplies (SMPS), power factor correction (PFC) stages, and inverters for motor drives and solar systems. Its low on-state resistance (R DS(on)) of just 0.19 Ω ensures minimal power dissipation during conduction, a critical factor for thermal management and energy savings.

Furthermore, the SPA16N50C3 features exceptional switching robustness and a very good body diode dv/dt capability. This inherent ruggedness enhances system reliability by ensuring stable operation under demanding conditions and hard commutation scenarios. The low gate charge (Q g) simplifies drive circuit design, reduces stress on the controller IC, and contributes to the reduction of switching losses.

In summary, the Infineon SPA16N50C3 represents a significant leap forward in high-voltage power switching. Its combination of ultra-low losses, high voltage capability, and robust switching characteristics makes it an ideal choice for designers aiming to push the boundaries of efficiency and power density in their next-generation products.
