Infineon IPB65R045C7: A High-Performance 650V CoolMOS™ CFD7 Power Transistor

The relentless pursuit of higher efficiency and power density in modern electronics, from server farms to electric vehicle chargers, demands continuous innovation in power semiconductor technology. At the forefront of this evolution is Infineon's IPB65R045C7, a 650V superjunction MOSFET that exemplifies the cutting-edge CoolMOS™ CFD7 technology. This device is engineered to set new benchmarks in performance, offering system designers a powerful component to push the boundaries of their applications.

A core differentiator of the CFD7 series, and this transistor in particular, is its exceptional balance between low switching losses and superior ease of use. Traditional high-voltage MOSFETs often force a trade-off between switching speed and electromagnetic interference (EMI). The IPB65R045C7 challenges this paradigm. Its integrated fast body diode and optimized internal cell structure ensure ultra-soft reverse recovery characteristics. This translates to significantly reduced voltage overshoot and lower switching losses, which not only boosts overall efficiency but also minimizes stress on the component and simplifies snubber circuit design, leading to higher system reliability.

The standout feature of this component is its industry-leading low on-state resistance, specified at a maximum of 45 mΩ. This remarkably low RDS(on) directly minimizes conduction losses, allowing for more efficient power transfer and reduced heat generation. This capability is crucial for achieving high efficiency in demanding continuous operation, enabling designers to create more compact solutions without compromising on thermal performance or resorting to excessive cooling mechanisms.

Furthermore, the device is characterized by its high dv/dt ruggedness and avalanche robustness. These features ensure operational stability and longevity even under the harsh conditions of switching power supplies, which are prone to voltage spikes and unpredictable load changes. This inherent ruggedness provides designers with a greater margin of safety, enhancing the durability of the end product.

Packaged in the robust and space-efficient TO-263-7 (D2PAK-7), the IPB65R045C7 is ideally suited for a wide array of high-performance applications. It is a prime candidate for use in:

Server & Telecom Power Supplies (PSUs)

Industrial SMPS (Switch-Mode Power Supplies)

Solar Inverters and Energy Storage Systems

Electric Vehicle Charging Infrastructure

Motor Drives and Control
