Introduction to UES1306

The UES1306 is a rectifier and a single-phase bridge rectifier that is designed to be utilized in surge protection applications and/or other similar applications where a full wave rectification is necessary. It is composed of two diodes in a single package, one protected in the anode and one in the cathode. The protected diode has a high creepage distance that makes it suitable for most applications.

Types of UES1306

The UES1306 comes in the form of a 400 V version and a 800 V version, both with extremely low reverse leakage current. The 400 V version requires an operating temperature between -65°C and 150°C, dissipating a forward surge current of up to 5.15 A. The 800 V version, on the other hand, requires an operating temperature between -55°C and 125°C, dissipating a forward surge current of up to 8 A. Both types have a high temperature rise of less than 50K.

Application Field of UES1306

The UES1306 is suitable for power supplies, UPS and other types of surge protection applications. It has a wide variety of input voltages and can be used in various application scenarios. It is also very reliable and can be used in high-altitude areas, where it is protected from temperature shocks and has a long operating life.

Working Principle of UES1306

The working principle of the UES1306 is fairly simple. It operates by controlling the leakage current in the diode and the forward voltage drop. The diode can be reversed biased when the forward current drops below a certain level, which prevents the diode from conducting any current. When a surge is detected, the diode will become forward biased and will begin to conduct current. When it reaches the breakdown threshold, the diode will create a large avalanche current, which will protect the device from damage.

Conclusion

The UES1306 is a single-phase bridge rectifier that is used in applications where a full wave rectification is necessary. It is available in a 400 V version and a 800 V version, both with extremely low reverse leakage current and high temperature rise. It is suitable for various surge protection applications and is reliable in high-altitude areas. Its working principle is based on the control of the reverse leakage current and forward voltage drop.
