Diodes are semiconductor components that have variable characteristics dependent on the direction of the current flow. Rectifier diodes are designed and manufactured to allow current flow in one direction, blocking reverse current flow. The RF081L2STE25 is a rectifier diode, operating at a maximum reverse voltage of 800V and a maximum forward current of 15A.

The RF081L2STE25 is manufactured in a TO-220AC package, which allows it to be used in high-temperature applications up to 175°C. The TO-220AC design also allows it to dissipate large amounts of power while remaining coolest in higher-voltage, higher-current applications. The diode also has an automatic inrush current limit technology, allowing it to be used in circuitry that requires protection during inrush moments, as well as decreased power consumption.

The primary application fields for the RF081L2STE25 includes AC/DC conversion, freewheeling, reverse current blocking, and any applications that require high specified forward current, voltage, and power. In most AC/DC and DC/DC converters, an array of rectifier diodes may be used in series and/or parallel to ensure the stable operation of the circuits. The RF081L2STE25 allows for a cost-efficient and space-saving solution for such applications.

The working principle of the RF081L2STE25 is quite straightforward. When forward-biased, the diode will act to block the flow of reverse current and as a low-friction medium for forward current flow. When reverse-biased, the diode acts to limit the current that can flow through the diode, thereby providing protection to the circuitry. This is achieved through the presence of a depletion region that surrounds the conductive region of the diode.

The RF081L2STE25 is ideal for applications that require high forward current, voltage and power levels, especially in high-temperature applications. Its automatic inrush current protection also makes it suitable to be used in most AC/DC and DC/DC converters. Its TO-220AC housing also allows efficient power dissipation, which allows the RF081L2STE25 to remain the coolest in higher-voltage, higher current applications.
