The ON Semiconductor UF4001 is a high-performance ultra-fast recovery rectifier designed for applications requiring low forward voltage drop and rapid switching. This rectifier is a preferred choice for power supply and conversion systems, as well as other circuits where efficiency and speed are critical.

With a reverse voltage of 50V and a forward current of 1.0A, the UF4001 is capable of handling moderate power levels while maintaining a low thermal resistance. This enables the device to operate at lower temperatures, thus enhancing reliability and extending its service life. Its ultra-fast reverse recovery time of 50ns minimizes power loss during the switching process, which is essential for high-frequency operations.

The UF4001 comes in a DO-41 axial-lead package, which is widely used and easy to integrate into various circuit designs. This package is known for its durability and its ability to withstand mechanical stress, making it suitable for a wide range of industrial and commercial applications.

Key features of the UF4001 include:

• Peak Repetitive Reverse Voltage (V<sub>RRM): 50V
• Average Rectified Forward Current (I<sub>o): 1.0A
• Maximum Instantaneous Forward Voltage (V<sub>F): 1.1V at 1.0A
• Maximum DC Reverse Current (I<sub>R): 10μA at 25°C
• Operating Junction Temperature Range: -55°C to +150°C
• Ultra-Fast Reverse Recovery Time: 50ns

The UF4001 is not only characterized by its performance but also by its environmental resilience. It complies with RoHS directives, which means it is manufactured without the use of hazardous substances. This compliance reflects ON Semiconductor's commitment to environmental sustainability and the production of eco-friendly components.

Whether you're designing power management systems, inverters, converters, or any application that demands efficient and fast switching, the ON Semiconductor UF4001 ultra-fast recovery rectifier is an excellent choice that combines performance, reliability, and environmental responsibility.
