Technical Overview and Key Features

The CoolMOS™ P7 is engineered to push the boundaries of what is possible in hard- and soft-switching topologies. The IPA60R180P7XKSA1 is a specific part within this series, characterized by its 600V drain-source voltage (VDS) and a maximum continuous drain current (ID) of 11.5A at 100°C.

Its standout performance is rooted in several groundbreaking features:

Ultralow Effective Output Capacitance (Eoss): This is arguably the most significant innovation. The P7 technology drastically reduces switching losses, particularly at light loads, which is crucial for achieving high efficiency across a wide load range. This makes it ideal for modern power supplies that must meet stringent energy efficiency regulations like 80 PLUS Titanium.

Exceptional Reverse Recovery Performance: The intrinsic body diode exhibits excellent reverse recovery characteristics, minimizing recovery losses and electromagnetic interference (EMI). This simplifies circuit design and reduces the need for additional snubber circuits.

High Robustness and Reliability: The device boasts a high avalanche energy rating and is qualified for industrial and consumer applications, ensuring long-term operational stability even under stressful conditions.

Optimized Gate Charge (Qg): A balanced ratio of on-state resistance (RDS(on)) to gate charge ensures efficient driving and fast switching speeds, further contributing to reduced overall losses.
