The S3740 is a single-phase silicon rectifier, specifically designed for applications that require a higher forward surge current than is available with conventional rectifier diodes. The high surge current capability of the S3740 enables its use in AC/DC converters, as well as other applications requiring high surge current capabilities. The S3740 also has a low forward voltage drop, making it an ideal choice for switching power applications.

The main component in the S3740 is a high-voltage power MOSFET. It consists of a N-channel MOSFET and a Schottky diode connected in parallel across the main drain and gate terminals. The MOSFET has a highly conductive and easily controllable gate, while the diode has a low forward voltage drop, making it ideal for rectifying AC power. By combining the two components into a single package, the S3740 provides significant improvement in the efficiency, power handling capacity and response time of the rectifier compared to discrete rectifier components.

The S3740 offers many advantages over conventional rectifier diodes, including lower forward voltage drop and higher surge current. The S3740 also has faster switching times than conventional rectifier diodes, making it ideal for switching power applications. Additionally, the S3740 can be used in power supplies with lower power levels, which provides increased system efficiency and improved protection against line disturbances.

The S3740 is a current-controlled device. The Schottky diode and MOSFET are connected in parallel, and the current is controlled by the gate voltage. When the gate voltage is increased, current increases, and the voltage across the diode and MOSFET increases accordingly. Conversely, when the gate voltage is decreased, the current decreases and the voltage across the diode and MOSFET decreases accordingly.

The S3740 also offers an improved temperature stability compared to conventional rectifier diodes. It has a temperature coefficient of less than twice standard rectifier diodes, which allows it to have a higher operating temperature range. Additionally, its fast switching times allow for higher current and power handling capabilities than standard rectifier diodes.

The S3740 is an ideal choice for a wide range of applications that require higher forward surge current compared to conventional rectifier diodes. It is well-suited for AC/DC converters, as well as for switching power applications where its higher surge current capability and faster switching times can be leveraged for improved efficiency, power handling and system protection.
