Infineon IRFP4468PBF N-Channel Power MOSFET Datasheet and Application Overview
The Infineon IRFP4468PBF is a high-performance N-Channel power MOSFET designed to meet the demanding requirements of modern power electronics. Utilizing Infineon's advanced proprietary process technology, this device is engineered for extremely low on-state resistance and high switching speed, making it an ideal choice for high-efficiency power conversion applications.
A thorough review of the datasheet reveals the key specifications that define this component's capabilities. The IRFP4468PBF is characterized by a drain-source voltage (Vds) of 150V and a continuous drain current (Id) of 130A at a case temperature of 100°C. Its most prominent feature is its exceptionally low typical on-resistance (Rds(on)) of just 3.6 mΩ at 10V gate drive. This low Rds(on) is critical for minimizing conduction losses, which directly translates to higher efficiency and reduced heat generation in operation. The device also features a low gate charge (Qg), which simplifies drive circuit design and minimizes switching losses, a vital factor for high-frequency switching power supplies.
The robust TO-247 package ensures superior thermal performance, allowing the MOSFET to handle high power dissipation. The datasheet provides detailed maximum ratings, safe operating area (SOA) graphs, and thermal characteristics that are essential for reliable system design. Designers must pay close attention to these limits to avoid catastrophic failure.
In application, the IRFP4468PBF excels in a wide array of circuits. Its primary use is in switching power supplies and DC-DC converters for servers, telecom equipment, and industrial machinery. It is also an excellent candidate for motor control and drive circuits, where its high current handling and ruggedness are major advantages. Furthermore, it is suitable for use in synchronous rectification stages of switched-mode power supplies (SMPS), leveraging its low Rds(on) to replace traditional diodes and significantly improve overall efficiency.
When designing with this MOSFET, careful consideration of the gate driver is paramount. A driver capable of delivering sufficient peak current is required to quickly charge and discharge the input capacitance, ensuring fast switching transitions and keeping the device within its SOA. Proper PCB layout for minimizing parasitic inductance and effective heatsinking are also critical for achieving optimal performance and long-term reliability.
