Introduction

A single-phase Schottky barrier rectifier (SRA8150 C0G) is a solid-state shunt device often used to convert AC voltage to a DC voltage. It has a low on-state voltage drop and a low reverse recovery charge, making it the preferred choice for overvoltage protection in power supplies and AC-DC converters. It is also used in higher power applications in a full-wave bridge configuration.

Application Field

The main application fields of an SRA8150 rectifier include overvoltage protection circuits, DC/DC converters, switched-mode power supplies (SMPS), high-voltage power supplies, and high-frequency applications.Overvoltage protection circuits are mainly used to prevent abnormal voltages in a circuit, and the SRA8150 is an ideal component for this application because of its low voltage drop and low reverse recovery charge.DC-DC converters are used to convert a DC power supply from one level of voltage to another. The reverse-recovery time of the SRA8150 is shorter than that of other rectifiers, which makes it much more efficient and suitable for high-frequency applications.Switched-mode power supplies (SMPS) are high-contrast, highly efficient power supplies that can supply a steady voltage level regardless of the load placed on them. The high-frequency switching of an SMPS requires a fast switching device with low reverse-recovery time and low voltage drop, and the SRA8150 meets these requirements.High-voltage power supplies (such as those used in electroplating) require rectifiers that can withstand high voltages and large currents, and the SRA8150 is up to this task.High-frequency applications, such as SMPS, radio-frequency applications, and pulse-type converters, require fast-switching rectifiers with low reverse-recovery time, and the SRA8150 is the perfect component for these applications.

Working Principle

The SRA8150 C0G rectifier works by providing a low forward voltage drop and a low reverse recovery charge, allowing most of the current to flow in the forward direction. When the supply voltage is greater than the forward voltage of the rectifier, the current flow is limited only by the external resistance in the circuit.The reverse voltage of the SRA8150 is zero, so it is an ideal device for overvoltage protection circuits. When the voltage in the circuit rises above the forward voltage of the rectifier, the current will flow in the opposite direction and be quickly blocked.When the reverse voltage of the SRA8150 is above its breakdown voltage, the current flow can be quite large, making it suitable for applications such as DC/DC converters and high-voltage power supplies.

Conclusion

The SRA8150 C0G rectifier is a versatile device with many applications. Its low on-state voltage drop and low reverse recovery charge make it ideal for overvoltage protection circuits, switched-mode power supplies, DC/DC converters, high-voltage power supplies, and high-frequency applications. It is a robust device with high current and voltage ratings, making it well suited for these applications.
