Mingjiada Electronics supplies the Infineon BSC160N15NS5 OptiMOS™ 5 150V N-channel MOSFET – a high-efficiency power switching solution for telecommunications infrastructure

I. BSC160N15NS5 Product Overview

Against the backdrop of telecommunications infrastructure continuing to evolve towards higher density and greater efficiency, the selection of power MOSFETs directly determines the conversion efficiency and long-term reliability of power supply systems. Infineon Technologies’ BSC160N15NS5, part of the OptiMOS™ 5 150V power MOSFET series, is housed in a SuperSO8 (TDSON-8) package. With an ultra-low on-resistance of 16 mΩ and a continuous drain current capability of 56 A, it is an ideal choice for synchronous rectification and high-frequency switching applications in 48 V power supply architectures within telecommunications infrastructure.

Mingjiada Electronics (Shenzhen Mingjiada Electronics Co., Ltd.), an authorised independent distributor of electronic components with nearly thirty years’ experience, has long provided a stable supply of the full range of Infineon MOSFET products, including the OptiMOS™ 5 power MOSFETs such as the BSC160N15NS5.

This device features a dual-sided cooling package design with extremely low junction-to-top thermal resistance, combined with an extremely low gate charge × on-resistance figure of merit (FOM) and extremely low reverse recovery charge, enabling it to significantly reduce switching and conduction losses in high-frequency switching and synchronous rectification applications.

III. Key Applications of the BSC160N15NS5 in Telecommunications Infrastructure

3.1 Synchronous Rectification in 48V DC-DC Converters

Modern telecommunications infrastructure widely employs 48V DC power distribution architectures. In high-frequency DC-DC converters with a 48V input, the secondary-side synchronous rectification MOSFET must simultaneously meet the dual requirements of low on-resistance and fast body diode recovery characteristics. The BSC160N15NS5’s ultra-low on-resistance of 16 mΩ and reverse recovery charge of just 26 nC enable it to effectively reduce rectification losses in synchronous rectification topologies, thereby improving the overall conversion efficiency of the system.

3.2 Switch-Mode Power Supplies (SMPS) in Telecommunications Equipment

Switch-mode power supplies in telecommunications base stations, routers and transmission equipment impose stringent requirements on the efficiency and thermal performance of power devices. The OptiMOS™ 5 150V series is explicitly listed by Infineon as the recommended choice for telecommunications infrastructure applications and is suitable for high-frequency switching scenarios such as power supplies for communications equipment and DC-DC power conversion.

3.3 48V Intermediate Bus Converters (IBC)

In data centres and telecommunications equipment rooms, 48V intermediate bus converters are responsible for converting voltage from the 48V bus to the point-of-load voltage. Thanks to its low FOM characteristics, the BSC160N15NS5 enables higher power density and lower temperature rise in IBC topologies.

3.4 Low-Voltage Drives and Solar Applications

In addition to telecommunications infrastructure, the BSC160N15NS5 is also suitable for low-voltage drives (such as electric forklifts and electric scooters) as well as solar inverters, demonstrating broad adaptability across various scenarios.
