Infineon BSZ018NE2LS: 30 V OptiMOS Power MOSFET for High-Efficiency Power Conversion
The relentless pursuit of higher efficiency and power density in modern electronics places immense demands on power management components. Addressing this need, the Infineon BSZ018NE2LS stands out as a premier 30 V N-channel power MOSFET built on Infineon's advanced OptiMOS™ technology. This device is engineered to deliver exceptional performance in a compact package, making it an ideal solution for a wide array of power conversion applications.
A key metric for any power switch is its on-state resistance, which directly impacts conduction losses and overall efficiency. The BSZ018NE2LS boasts an extremely low typical RDS(on) of just 1.8 mΩ at 10 V. This remarkably low resistance ensures minimal voltage drop and power dissipation when the device is fully turned on, which is critical for maintaining high efficiency, especially in high-current scenarios. This characteristic makes it perfectly suited for demanding roles such as synchronous rectification in switch-mode power supplies (SMPS) and load switching in automotive systems.
Beyond its low RDS(on), the MOSFET features a low gate charge (Qg) and exceptional switching performance. These attributes are paramount for high-frequency operation, as they significantly reduce switching losses. Designers can leverage this to increase the switching frequency of their power supplies, which in turn allows for the use of smaller passive components like inductors and capacitors. This leads to the development of more compact, lighter, and higher power-density end products.
Housed in a space-saving SuperSO8 package, the BSZ018NE2LS offers an excellent thermal footprint. Its superior package design enhances heat dissipation, allowing the component to operate reliably under continuous high-load conditions. This robust thermal performance is essential for ensuring long-term system reliability and stability.

The combination of ultra-low resistance, fast switching speed, and a thermally efficient package positions the BSZ018NE2LS as a top-tier component for maximizing efficiency in modern power electronics. It is extensively used in:
DC-DC conversion modules for computing and telecom infrastructure.
Motor control circuits in industrial automation and consumer appliances.
Battery management systems (BMS) and other automotive applications.
