Infineon IPD090N03LG 60V OptiMOS Power Transistor: Key Features and Applications

The Infineon IPD090N03LG represents a significant advancement in power semiconductor technology, belonging to the renowned OptiMOS family. This 60V N-channel power MOSFET is engineered to deliver exceptional efficiency, reliability, and performance in a compact package, making it an ideal choice for a wide array of modern power management applications.

Key Features

At the core of the IPD090N03LG's superiority is its extremely low on-state resistance (RDS(on)) of just 0.9 mΩ. This minimal resistance is crucial as it directly translates to reduced conduction losses, allowing the transistor to operate with higher efficiency and generate less heat. This feature is paramount for improving the overall thermal performance and energy savings in any system.

Complementing its low RDS(on) is the low gate charge (Qg). A lower gate charge enables faster switching speeds, which minimizes switching losses—a critical factor in high-frequency applications. This combination of low resistance and low gate charge ensures that the device operates efficiently even at high switching frequencies.

Furthermore, the device is housed in a space-saving DSO-8 (SuperSO8) package. This compact footprint is essential for modern electronics where board space is at a premium, allowing designers to create more powerful and dense systems without compromising on performance. The package also offers enhanced thermal characteristics, facilitating effective heat dissipation and contributing to the device's overall robustness and long-term reliability.

Primary Applications

The blend of high efficiency, fast switching, and a small form factor makes the IPD090N03LG exceptionally versatile. Its primary applications include:
