STPS30L30CG is an array of three 30A, 600V power Schottky rectifiers in a molded butyl rubber package. It is a three phase device, suitable for a wide range of electronic applications. In this article we will look at the application field of STPS30L30CG and its working principle.

Application Field

The STPS30L30CG is mainly used as a rectifier in high-power AC/DC power supplies and as a freewheeling diode in motor controllers. It is also suitable for voltage-doubling applications, and can be used as an auxiliary rectifier in battery charging systems. It can also be used in voltage clamping and dc-to-dc converters. The device offers superior thermal performance compared with other rectifier packages, making it ideal for use in applications with high current flows.

Working Principle

The STPS30L30CG is a three phase Schottky rectifier that provides efficient rectification of three-phase AC power. It is a three-terminal device, with one common cathode, three anodes, and one gate. When the gate is driven with a suitable signal, the device can be configured as either a forward rectifier or a freewheeling diode. In its forward rectifier mode, the STPS30L30CG acts like a switch, allowing the positive half of each cycle of the input current to flow through the device and generate output current in the positive direction. In the freewheeling diode mode, the device acts like a non-conducting diode, allowing the negative half of each cycle of the input current to bypass the device and generate output current in the negative direction. The device also has a low forward voltage drop, allowing it to operate efficiently at high frequencies.

Conclusion

The STPS30L30CG is an array of three 30A, 600W power Schottky rectifiers. It is suitable for a wide range of electronic applications, including AC/DC power supplies, motor controllers, voltage-doubling applications, battery charging systems, and dc-to-dc converters. Its three-terminal structure allows it to be configured as either a forward rectifier or a freewheeling diode, making it suitable for high-frequency applications. The device offers superior thermal performance compared with other rectifier packages, making it ideal for use in applications with high current flows.
