UG2DHA0G is a dual Schottky rectifier with integrated antiparallel diode, consisting of two independent Schottky-barrier rectifier semiconductor dies. It is widely used in modern switch-mode power supplies, AC and DC/DC converters, and various end uses, such as DC motors, battery chargers and similar applications at high frequencies.

It features a low-profile, surface-mount package and a very low reverse leakage current; in addition, it offers a very low forward voltage drop, lower than those of traditional Schottky rectifiers. The forward voltage drop of UG2DHA0G is between 0.65 volts (2 amps) and 0.45 volts (5 amps), which is much lower than the forward voltage drop of a traditional Schottky diode, typically around 0.7V.

The low forward voltage drop of UG2DHA0G allows for more efficient power conversion compared to traditional Schottky diodes, offering improved current-handling capabilities. Additionally, it offers a wide operating temperature range of -65°C to + 175°C, which allows the device to operate in a wide range of temperature conditions, while maintaining its superior performance. Furthermore, the device is rated for a repetitive reverse voltage of 20V and has a peak forward surge current of 4A.

The working principle of UG2DHA0G is based on the principle of the Schottky rectifier. When a voltage is applied across the anode and cathode terminals, a forward bias is created, allowing current to flow through the rectifying element. As the voltage and current increase, the voltage drop across the rectifying element decreases. This phenomenon is known as the forward voltage drop, or Vf. As the voltage and current increase, the device’s forward voltage drop continues to decrease, resulting in higher power efficiency and current-handling capabilities.

The device also operates under what is known as a “reverse bias” condition. Here, the current flow is opposite to the traditional forward bias current. In this condition, the device’s reverse leakage current increases exponentially. This phenomenon is known as the reverse leakage current, or IR.

In summary, UG2DHA0G is a dual-diodes Schottky rectifier with integrated antiparallel diode. It offers a very low forward voltage drop and a wide operating temperature range. It features a low-profile, surface-mount package and a very low reverse leakage current, enabling efficient power conversion in demanding applications. It is widely used in modern switch-mode power supplies, AC and DC/DC converters, and various end uses, such as DC motors, battery chargers and similar applications at high frequencies.
