Infineon BSZ075N08NS5ATMA1: High-Performance 80V OptiMOS Power MOSFET for Efficient Power Conversion

The relentless pursuit of higher efficiency, power density, and reliability in modern electronics drives continuous innovation in power semiconductor technology. At the forefront of this evolution is Infineon Technologies with its OptiMOS™ power MOSFET family. The BSZ075N08NS5ATMA1 stands as a prime example, an 80V N-channel MOSFET engineered to set new benchmarks in performance for a wide array of power conversion applications.

This MOSFET is built upon Infineon’s advanced superjunction technology, which is the cornerstone of its exceptional characteristics. The device boasts an extremely low typical on-state resistance (R DS(on)) of just 0.75 mΩ, a critical factor in minimizing conduction losses. When a high current flows through the switch, a lower R DS(on) translates directly into less energy being wasted as heat. This inherent efficiency is paramount for applications like server and telecom power supplies, where energy loss impacts operational costs and thermal management complexity.

Beyond static losses, switching performance is crucial for high-frequency operation. The BSZ075N08NS5ATMA1 features outstanding switching characteristics and a low gate charge (Q G). This combination allows for faster switching speeds, which enables power supply designers to increase the switching frequency of their designs. A higher frequency, in turn, permits the use of smaller passive components like inductors and capacitors, leading to a significant increase in overall power density – a key requirement for compact modern hardware.

The device’s 80V drain-source voltage rating provides a comfortable safety margin in 48V intermediate bus architectures common in datacom and automotive systems, ensuring robust operation and reliability. Furthermore, it is housed in a SuperSO8 package, which offers a superior thermal performance compared to standard SO-8 packages. This enhanced thermal efficiency ensures that the MOSFET can operate effectively under continuous load without overheating, contributing to the long-term longevity of the end product.

Qualified for industrial and automotive applications, the BSZ075N08NS5ATMA1 is an ideal solution for:

Synchronous rectification in switch-mode power supplies (SMPS)

DC-DC converters for computing and communication infrastructure

Motor drive and control circuits

High-performance power tools
