SF2003PTHC0G

Diodes - Rectifiers - Single

A single-phase rectifier is a device that is used to convert alternating current (AC) to direct current (DC). It is also known as an AC-DC converter. SF2003PTHC0G is a single-phase rectifier with fast recovery characteristics.

General Description

The SF2003PTHC0G is a single-phase rectifier with a fast recovery diode in the PTHC0G package. It has a maximum DC forward continuous current rating of 200A at a maximum case temperature of 125°C and a non-repetitive surge peak rating of 600A for 10 seconds. The reverse voltage rating of this rectifier is 1.5kV with a peak repetitive reverse voltage of 1kV. It has a forward voltage drop of 1.75V maximum at 200A.

Applications

The SF2003PTHC0G is suitable for general purpose applications such as power supplies, motor control, telecommunication, and solar panel rectifiers, among many others. It is also suitable for AC to DC conversion circuits and automotive applications.

Working Principle

The SF2003PTHC0G rectifier works on the principle of the conversion of alternating current to direct current by using a diode bridge and other components for rectification. The AC input is applied across the diode bridge, which is composed of four diodes, arranged in a way so that in each cycle of the AC one diode conducts and the other three act as shunts. This type of component provides high efficiency and low energy loss due to the absence of a transformer. As the diode conducts, it will allow only one half cycle of the AC to pass through the component to the load. This is known as half-wave rectification and yields a pulsating DC voltage. To get a smooth DC voltage, a filter needs to be used.

Advantages

The SF2003PTHC0G rectifier offers several advantages over other components such as low power consumption, high reliability, low reverse recovery time, and low EMI. Furthermore, it is designed to be thermally- and electro-efficient, providing a great deal of power in a small package.

Conclusion

The SF2003PTHC0G rectifier is an efficient power conversion device used in numerous applications. It is capable of providing high current and voltage ratings, along with low power consumption and high reliability. It is well-suited for automotive, general purpose, and telecommunication applications.
