Diodes - Rectifiers - Single, S3G-E3/57T, are global stud type rectifiers with a low forward voltage drop, these rectifiers are suitable for use with medium current freewheeling, as well as other general purpose applications over a wide range of operating temperature and voltage range.

The S3G-E3/57T can handle forward currents of up to 0.6A and peak transient currents of up to 20A, and features a low forward voltage of 1.10V. Built on an electrically insulated compact heat sink and using a low profile, these rectifiers are easy to install and are suitable for a variety of applications.

The S3G-E3/57T is a sealed type rectifier diode with a stud terminal connection. It is constructed using a ceramic substrate with two layers of contacts: the anode and cathode. As a single rectifier, it is capable of producing a single rectified output. The maximum rated power is 2.5W, meaning it has a maximum voltage rating of 600V and a maximum current rating of 0.6A.

The working principle of the S3G-E3/57T is relatively simple. When an AC current is applied to the rectifier, the anode lead acts as a conducting part and the cathode acts as a non-conducting one. During the positive half cycles of the applied AC current, the anode is more positive compared to the cathode and hence, current flows from the anode to the cathode. This current flow is named positive half-cycle current by rectifiers.

During the negative half-cycle of the applied AC current, the cathode becomes more positive compared to the anode and hence, current does not flow from the anode to the cathode. This absence of significant negative current flow is what gives the S3G-E3/57T its rectifying capability.

Due to its high performance, the S3G-E3/57T is used in a wide range of applications such as motor drives, LED lighting, battery chargers and inverters. It is also widely employed in industrial controls and renewable energy power conversion systems.

The S3G-E3/57T also offers a high reliability and on-state current capability, making it applicable for temperature-sensitive application. The S3G-E3/57T is able to operate over a wide temperature range of -55C to +175C and offers an increased on-state current capability of up to 0.50A at +25C.

The S3G-E3/57T is able to provide an ideal solution to applications with low noise requirements. With low transitions times of 2nsec at a forward current of 0.6A and 600mV of forward voltage, the S3G-E3/57T ensures minimal switching noise.

In conclusion, the S3G-E3/57T is a low forward voltage drop and medium current freewheeling rectifier with a low profile and excellent performance features, making it highly suitable for use in a wide range of applications. It is able to offer a high reliability and on-state current capability, and is able to operate over a wide temperature range.
