Infineon IPP045N10N3GXKSA1: A 100V OptiMOS 5 Power MOSFET for High-Efficiency Applications

The relentless pursuit of higher efficiency and power density in modern electronics drives the continuous innovation in power semiconductor technology. At the forefront of this innovation is Infineon's OptiMOS™ 5 power MOSFET family, with the IPP045N10N3GXKSA1 standing out as a premier solution for demanding high-efficiency applications. This 100V N-channel MOSFET is engineered to minimize losses and maximize performance in a compact package.

A key strength of the IPP045N10N3GXKSA1 lies in its exceptionally low figure-of-merit (FOM), characterized by an ultra-low on-state resistance (R DS(on)) of just 3.5 mΩ maximum at 10 V. This is combined with outstanding switching performance, thanks to its low gate charge (Q G). The low R DS(on) directly translates to reduced conduction losses, allowing the device to handle high currents with minimal voltage drop and heat generation. Concurrently, the low gate charge ensures swift and efficient switching transitions, which is critical for high-frequency operation. This combination is paramount for achieving peak efficiency in applications like switch-mode power supplies (SMPS) and motor control.

The device is housed in an TO-leadless (TOLL) package, which offers a significantly reduced footprint and profile compared to standard packages like D2PAK. This package not only saves valuable PCB space, crucial for today's compact designs, but also features an exposed top side for superior thermal management. This allows for highly efficient heat dissipation, enabling the MOSFET to operate reliably at high power levels. The 100V voltage rating provides a robust safety margin, making it an ideal choice for 48V bus systems common in telecom, server, and industrial environments, as well as for synchronous rectification in AC-DC converters.

Typical applications that benefit from the IPP045N10N3GXKSA1's prowess include:

High-Current DC-DC Converters in server and data center power supplies.

Synchronous Rectification stages in AC-DC adapters and SMPS.

Motor Drive and Control Circuits for industrial automation and robotics.

Solar Inverters and other renewable energy systems.
