Infineon BSC120N03MS: High-Performance 30V MOSFET for Power Management Applications

The Infineon BSC120N03MS is a state-of-the-art N-channel MOSFET engineered to deliver exceptional performance in a wide array of power management applications. Built on Infineon’s advanced OptiMOS™ technology, this 30V MOSFET sets a high standard for efficiency, power density, and reliability, making it an ideal choice for demanding modern electronics.

A key strength of the BSC120N03MS lies in its extremely low on-state resistance (RDS(on)) of just 1.2 mΩ. This minimal resistance is critical for reducing conduction losses, which directly translates to higher system efficiency and less heat generation. The result is a cooler-running, more reliable design that can operate at peak performance for longer durations. Furthermore, its low gate charge (Qg) ensures swift switching transitions, minimizing switching losses—a vital characteristic for high-frequency switching regulators and converters. This combination of low RDS(on) and Qg makes the device exceptionally efficient, particularly in power-dense applications where thermal management is a primary concern.

The MOSFET’s 30V drain-source voltage rating makes it perfectly suited for a broad spectrum of low-voltage applications. It is extensively used in synchronous rectification in DC-DC converters, voltage regulation modules (VRMs) for servers and computing hardware, and load switch circuits in consumer electronics. Its robust design and high performance also make it an excellent fit for power management in automotive systems, such as motor control and battery management systems (BMS), where both efficiency and durability are non-negotiable.

Packaged in a compact and industry-standard SuperSO8 (SSO-8) housing, the BSC120N03MS offers an excellent balance between power handling capability and board space savings. This allows designers to create more compact and lighter end-products without compromising on performance or thermal behavior.

ICGOODFIND: The Infineon BSC120N03MS is a top-tier 30V MOSFET that excels in minimizing power losses and maximizing power density. Its superior efficiency and thermal performance, driven by ultra-low RDS(on) and Qg, make it a premier solution for advanced power management designs in computing, automotive, and industrial applications.
