Infineon SAKC505CA-4EM: High-Performance 500V CoolMOS™ P7 Power Transistor

In the realm of power electronics, efficiency, reliability, and thermal performance are paramount. The Infineon SAKC505CA-4EM stands as a pinnacle of these qualities, representing the advanced CoolMOS™ P7 technology platform. This 500V superjunction MOSFET is engineered to deliver exceptional performance in a wide array of high-efficiency applications, from server and telecom SMPS (Switched-Mode Power Supplies) to industrial motor drives and renewable energy systems.

At the core of the SAKC505CA-4EM is its revolutionary superjunction structure. This design is the key to achieving an incredibly low specific on-state resistance (R DS(on)) for a given die size. The result is a device that minimizes conduction losses, allowing for higher power density and efficiency. Designers can create more compact, lighter, and cooler-running systems without sacrificing performance or robustness.

A critical advantage of the CoolMOS™ P7 series is its enhanced switching behavior. Despite its high-voltage rating, the transistor exhibits low gate charge (Q G) and low effective output capacitance (C OSS(eff)). This translates to significantly reduced switching losses, especially at higher frequencies. This characteristic is crucial for modern power supplies aiming to meet stringent energy efficiency standards like 80 Plus Titanium, as it enables operation at higher switching frequencies, which in turn reduces the size of passive components like magnetics and capacitors.

The SAKC505CA-4EM is also designed with robustness and ease of use in mind. It features a high body diode robustness (dv/dt capability), ensuring reliable operation in hard-switching and inductive load conditions. Furthermore, its avalanche ruggedness provides an added layer of protection against voltage transients and unclamped inductive switching (UIS) events, enhancing the overall reliability of the end application. Housed in a TO-220 package, it offers a classic and versatile footprint for both through-hole and mounting applications, with excellent thermal characteristics.

ICGOOODFIND Summary: The Infineon SAKC505CA-4EM CoolMOS™ P7 is a benchmark 500V power MOSFET that masterfully balances ultra-low losses, high switching speed, and superior ruggedness. It is an optimal choice for engineers pushing the boundaries of power density and efficiency in next-generation AC-DC conversion and power management systems.
