UG2A-E3/54

Diodes - Rectifiers - Single

The UG2A-E3/54 is a single-phase bridge rectifier that consists of four independent ultra-fast blocking diodes in a single package. It is suitable for high forward surge current, DC rectification and stabilizing applications. This rectifier can be used in industries such as automotive, telecommunication, consumer electronics, computer and other general purpose applications.

The UG2A-E3/54 utilizes a proprietary glass passivated chip diode technology to achieve a high reverse voltage capability. This glass passivation ensures a high dielectric strength and junction passivation, providing additional stability. It is designed with a shield that protects against environmental pollutants and improves switching stability by minimizing noise generation.

The UG2A-E3/54 has a high surge current capability and can withstand repetitive peak reverse voltages up to 1000V. This bridge rectifier has fast switching speed of up to 100V/�s. It maintains a low forward voltage drop and low power loss. It also has a maximum junction temperature of 150�C, which allows it to operate in high temperature environments.

Application Fields

The UG2A-E3/54 can be used for industrial and domestic applications such as motor drives, household appliances, power supplies and audio amplifiers. It can be used in circuit boards, power supplies, and other electronics systems because of its compact design. It is also suitable for system isolation, power factor corrections, current limiters and other applications where electronic protection is desired.

Working Principle

The UG2A-E3/54 is a single-phase bridge rectifier that consists of four independent ultra-fast blocking diodes. The Polarity of each diode depends on its position. The first diode acts on the positive cycle and the second one acts on the negative cycle. The diodes are arranged in a bridge configuration and the forward charges are blocked from the output. The output of the rectifier is a pulsed DC current. The diodes allow current to flow only in one direction, thereby acting as a reverse-current protection device to prevent overvoltage.

In a rectified signal, the positive cycle output has a higher amplitude than the negative cycle output. This causes a voltage spike or ringing in the output signal. The UG2A-E3/54 has a low-impedance bridge rectifier that reduces the ringing effect. This bridge rectifier also has a low peak forward voltage drop, resulting in minimal power loss. The high surge rating of the rectifier also helps to reduce the power losses caused by sudden changes in the load current.

The UG2A-E3/54 is an ideal choice for many applications, due to its high surge current capability and its ability to resist high reverse voltages. The diodes used in this rectifier have a fast switching speed and a low forward voltage drop. The bridge rectifier has a low-impedance design that reduces the ringing effect in a rectified signal. The UG2A-E3/54 can be used in applications such as motor drives, power supplies, power factor corrections and other applications where electronic protection is desired.
