UG2B-E3/73

The UG2B-E3/73 is a special rectifier diode designed to perform both rectification and fast switching duties in bridges, inverters, and motor control circuits. It can handle very high currents and has a low forward voltage drop. It has an ultra-fast reverse recovery time, making it ideal for switching applications. It is also practical for use in high power applications such as power supplies and inverters.

Design Features and Benefits

The UG2B-E3/73 has several important design features that make it a valuable choice for many applications. First, its high working current rating of 73A makes it ideal for switching applications where high current is involved. It also has an extremely low forward voltage drop of 0.361V, making it well-suited for use in rectifier bridge circuits. Additionally, its high thermal resistance of 0.105℃/W allows it to operate at higher temperatures without becoming thermally saturated.

Working Principle

The working principle of the UG2B-E3/73 is based on the rectification of alternating current (AC) into direct current (DC). This is accomplished by passing current through the diode in a switched, unidirectional manner. As the diode current passes through it, the diode acts as a switch, allowing current to flow in the forward direction but blocking any Reverse current. This creates a DC voltage waveform with a short “on” period and a longer “off” period.

Application Fields

The UG2B-E3/73 is ideal for use in a variety of applications, including switch mode power supplies, DC-DC converters, power inverters, motor control circuits, and rectifier bridges. Its high current rating and fast reverse recovery time make it well suited for switch-mode power supplies and other high-frequency applications. It can also be used to efficiently rectify AC inputs in motor controller, DC-DC converter and inverter circuits. Additionally, its low forward voltage drop makes it suitable for rectifier bridge applications requiring high-efficiency current conversion.

The UG2B-E3/73 is a rugged and reliable single rectifier diode with several design features that make it well suited for a wide range of applications, including switch mode power supplies, DC-DC converters, power inverters, motor control circuits, and rectifier bridges. Its high current rating, fast reverse recovery time, and low forward voltage drop make it an excellent choice for a variety of rectification and switching duties.
