It features low forward voltage drop, low power loss and low forward leakage current.

Applications

The FFSH2065A can be used in consumer applications, such as LED drivers, power supplies, battery chargers, and various DC-DC converters. It can also be used in automotive and industrial applications, such as motor controls, solar and wind power systems, and electric vehicles. It is also well suited for AC/DC rectification applications, since it has low reverse recovery time and high current capability.

Working Principle

The FFSH2065A is an example of a Schottky barrier diode. It has a unique structure that includes a thin layer of semiconductor material at the interface between the anode and the cathode. This layer of material creates a Rectifying Junction or a Schottky Barrier, which allows current to flow in only one direction and results in a low forward voltage drop. The device is designed with the Schottky barrier directly under the anode for low reverse recovery time and lower dynamic losses.

When the FFSH2065A is forward biased, the electrons flow from the cathode to the anode. The circuit is designed in such a way that the barrier resists any reverse current flow, thus only allowing forward current to flow through the device. This results in low power loss and low forward leakage current. As the voltage increases, a junction capacitance is produced which causes the anode to discharge into the cathode, resulting in a reverse recovery time of 1.0µs.

Conclusion

The FFSH2065A is a Schottky barrier rectifier, designed for high frequency, high current and low voltage applications. It features low forward voltage drop, low power loss and low forward leakage current. It is ideal for consumer, automotive and industrial applications, such as LED drivers, solar and wind power systems, and electric vehicles. The device has a low forward voltage drop and a low reverse recovery time of 1.0µs, making it suitable for AC/DC rectification applications.
