Single rectifier diodes are commonly used in power supplies, DC-DC converters, solar cells and other devices that rely on DC power. The S85KR diode is a two-terminal device that blocks current flow in one direction while allowing current flow in the opposite direction. It provides electrical isolation to protect sensitive components by blocking direct electrical connection.

The S85KR is a high-performance, high-power rectifier diode used in both high-voltage (up to 1000V) and high-current (up to 8A) applications. It is designed to work in applications where low forward voltage drop, low reverse leakage current and excellent surge current capability are desired. It is used in a variety of applications, from lighting, to motor drives, to power supplies and rectification.

A rectifier diode consists of an intrinsic semiconductor material, such as silicon, and two electrodes. The S85KR uses a base layer of silicon and a highly doped layer of N-type silicon to form the diode junction. An additional layer of doped P-type silicon at the junction aids in the reverse blocking characteristics of the device.

The S85KR is a high-power rectifier diode with a variety of features. It has a low forward voltage drop and minimal reverse current, which makes it an ideal choice for high power applications such as power supplies and AC-DC converters. The diode recovers quickly after current surges, making it an ideal choice for transient power and protection applications. Additionally, the S85KR offers high thermal stability and high surge capability. Finally, the S85KR is designed to operate up to a temperature of +175°C, making it suitable for many high-temperature applications.

The S85KR works by allowing current flow in one direction (forward direction) and blocking current flow in the opposite direction (reverse direction). When the voltage at the anode is greater than the voltage at the cathode, a flow of electrons occurs from the anode to the cathode. This forward current flow is regulated by the built-in diode junction. When the voltage at the anode is lower than the voltage at the cathode, a blocking current begins and the diode prevents any further current flow. This reverse blocking current is limited by the diode junction.

In summary, the S85KR rectifier diode is a high-power, high-performance device that can be used in a variety of applications such as lighting, motor drives, power supplies and rectification. It offers low forward voltage drop, a low reverse leakage current, high surge capability, thermal stability, and high temperature operation. The diode provides the ability to selectively allow and block current flow, providing the necessary protection and operation in many different applications.
