Infineon BSZ42DN25NS3: High-Performance 25V OptiMOS Power MOSFET
In the realm of power electronics, efficiency, thermal performance, and reliability are paramount. The Infineon BSZ42DN25NS3 stands out as a premier solution, engineered to meet the rigorous demands of modern applications. As part of Infineon’s esteemed OptiMOS™ power MOSFET family, this 25V N-channel MOSFET is designed to deliver exceptional performance in a compact package.
One of the most striking features of the BSZ42DN25NS3 is its extremely low on-state resistance (RDS(on)), which is as low as 0.55 mΩ. This ultra-low resistance is critical for minimizing conduction losses, leading to higher efficiency and reduced heat generation. Whether deployed in synchronous rectification, motor control, or high-frequency DC-DC converters, this MOSFET ensures that energy is utilized effectively, which is especially vital for battery-powered devices where every watt counts.

The device also excels in switching performance. With optimized gate charge (Qg) and figure of merit (FOM), it enables fast and efficient switching operations. This capability is indispensable in applications requiring high frequency and rapid response, such as in server power supplies, industrial drives, and automotive systems. The reduced switching losses contribute to cooler operation and allow for higher power density designs, giving engineers the flexibility to create more compact and powerful end products.
Thermal management is another area where the BSZ42DN25NS3 shines. Housed in an advanced SuperSO8 package, it offers superior thermal conductivity and power dissipation compared to standard SO-8 packages. This robust thermal performance ensures reliability even under high-stress conditions, extending the lifespan of both the component and the overall system.
Furthermore, Infineon has built this MOSFET with quality and durability in mind. It is characterized by high avalanche ruggedness and a broad safe operating area (SOA), making it a dependable choice for challenging environments. Its high reliability and performance consistency make it suitable for automotive applications, adhering to stringent industry standards.
