Diodes - Rectifiers - Single

The SBR8050E3 is a single-phase surface mount rectifier bridge with a metal stud faston tab terminal. With the metal stud faston terminal, it can be easily connected with other components to work as a bridge in numerous applications. The device is typically used for rectification in switching mode power supplies (SMPSs) and power factors corrections mills, as well as for general purpose rectification.

SBR8050E3 is available in a lead-free RoHS-Compliant package from a number of vendors. It has a maximum rating of 800V and can handle up to 50A surge current. The device also has a VF max of 1.3V at 90A. It features a suitably adapted lightning surge current, making it suitable for lightning testing.

Application Field

The SBR8050E3 rectifier bridge is widely used in many power conversion applications such as switch-mode power supplies (SMPSs), AC/DC adapters, and power factor correction circuits. Its surge capability of 50A makes it suitable for applications such as computers, UPS systems, servers, telecommunications equipment, and power supplies.

The SBR8050E3 is also used in induction heating circuits. It is highly suitable for rapid hardening of metals. It is also used in DC choppers and DC drives, switching circuits as well as various circuit protection applications.

Working Principle

The SBR8050E3 is a single-phase bridge rectifier with four diodes electrically configured as a bridge. The bridge rectifier consists of two DC load lines, one positive and one negative, along with four diodes connected in a bridge formation. The AC input is connected to the two ends of the bridge rectifier and the DC output is taken from the center of the bridge.

When an AC voltage is applied to the bridge rectifier, the diodes alternate between conducting and non-conducting states when the terminals of the diode become forward biased sequentially. When a diode is forward biased, it conducts the AC current and this current is rectified and appears across the load as direct current. The bridge rectifier also has a self-rectification property, where the rectified current will cause a certain amount of forward bias voltage across two diodes.

The SBR8050E3 has a maximum rating of 800V and can handle up to 50A surge current. This makes it very suitable for applications that require the rectification of higher voltage and current levels. Additionally, the device also features a suitably adapted lightning surge current rating, making it a suitable choice for lightning testing.

The SBR8050E3 can be used in a wide range of applications, ranging from AC/DC power supplies to general-purpose rectification and power factor correction circuits. Its excellent surge capability and lightning surge current rating make it a versatile and reliable component for both medium and high power applications.
