Infineon BSC032N03SG 30V Power MOSFET Datasheet and Application Review

The Infineon BSC032N03SG is a highly efficient N-channel power MOSFET designed using Infineon’s advanced OptiMOS™ technology. Optimized for low on-state resistance and high switching performance, this 30V MOSFET is ideal for a wide range of power management applications, particularly where high efficiency and power density are critical.

With a continuous drain current rating of 100 A and an ultra-low typical RDS(on) of just 3.2 mΩ at 10 V gate drive, the BSC032N03SG significantly reduces conduction losses. This makes it exceptionally suitable for high-current DC-DC conversion in systems such as server power supplies, telecom modules, and high-performance computing units. The low gate charge (Qg) and figure of merit (FOM) further enhance its efficiency in high-frequency switching circuits.

The device is housed in a SuperSO8 package, which offers improved thermal performance and power dissipation compared to standard SO-8 packages. Its compact footprint supports space-constrained PCB designs while maintaining robust operation under demanding conditions. The MOSFET also features a low thermal resistance and is designed to handle high peak currents, making it reliable in overload and surge scenarios.

Applications include synchronous rectification in switched-mode power supplies (SMPS), motor control systems, and battery management solutions. Its fast switching characteristics help in minimizing switching losses, thereby improving overall system efficiency. Engineers value this component for its repeatable performance and durability, backed by Infineon’s quality and reliability standards.

ICGOOODFIND: The Infineon BSC032N03SG stands out as a high-performance power MOSFET offering an exceptional balance of low RDS(on), high current capability, and thermal efficiency. It is an excellent choice for designers aiming to improve power density and energy efficiency in modern electronic systems.
