Infineon IPT059N15N3ATMA1: A High-Performance OptiMOS 5 Power MOSFET for Advanced Switching Applications

The relentless pursuit of higher efficiency, power density, and reliability in modern electronics drives the continuous innovation in power semiconductor technology. At the forefront of this innovation is Infineon Technologies' OptiMOS™ 5 family, with the IPT059N15N3ATMA1 standing out as a premier solution for demanding switching applications. This N-channel power MOSFET, built on an advanced trench technology, sets a new benchmark for performance in a compact, thermally enhanced package.

Engineered for exceptional switching efficiency, the IPT059N15N3ATMA1 is characterized by its ultra-low figure-of-merit (R DS(on) x Q G). With a maximum drain-source voltage (V DS) of 150 V and a continuous drain current (I D) of 170 A at 25°C, this device is adept at handling high power levels. Its standout feature is an incredibly low on-state resistance (R DS(on)) of just 5.9 mΩ maximum at 10 V, which is a key contributor to minimizing conduction losses. This low R DS(on), combined with superior gate charge (Q G) characteristics, ensures that the MOSFET switches rapidly and with minimal energy loss, making it ideal for high-frequency operation.

The device is encapsulated in a SuperSO8 (PG-TDSON-8) package, which offers a significantly improved thermal footprint compared to standard SO-8 packages. This advanced packaging technology enhances power dissipation capabilities, allowing for higher current handling and more reliable operation under strenuous conditions. The low parasitic inductance of the package also contributes to reduced voltage overshoot during switching, further enhancing system reliability and performance.

The primary application domains for the IPT059N15N3ATMA1 are high-performance switched-mode power supplies (SMPS), server and telecom power systems, and high-current DC-DC converters. It is also exceptionally well-suited for synchronous rectification stages in modern power supply topologies, where its fast body diode and excellent reverse recovery characteristics are critical for minimizing losses. Furthermore, its robustness and efficiency make it a prime candidate for motor control and drive circuits in industrial automation, as well as in energy-intensive applications like solar inverters and battery management systems.
