Diodes are an essential component in any basic circuit, acting as a type of switch to control current flow. Bridge rectifiers are a specific type of diode that are commonly found in power supplies or any other application where DC voltage is needed from an AC source. The APT75DL120HJ is a bridge rectifier manufactured by APT Components, designed for general purpose use in a wide variety of applications. This article will discuss the application fields and working principles of the APT75DL120HJ.

Features

The APT75DL120HJ is an ultra-low profile bridge rectifier with a typical profile of 0.75mm. It offers high efficiency performance in a wide range of applications where space is at a premium. It is built with a plastic mold package and supports a rated repetition frequency of up to 150kHz. Other features of the APT75DL120HJ include its wide common-mode range and its ability to withstand high surge currents.

Application Fields & Working Principle

The APT75DL120HJ is capable of application fields such as power supplies, DC motors, power adapters and automotive use. Its working principle is based on the four diodes that form a bridge configuration. When a single-phase input voltage is connected to the bridge rectifier, the positive half of the input voltage turns on two of the diodes, and the other two diodes will be turned on when the negative half of the input voltage is applied. Thus, the diode bridge is able to pass both positive and negative currents, and the resulting output voltage across the bridge rectifier is DC voltage.

The APT75DL120HJ is designed to operate in applications with a maximum input voltage of up to 75V and a maximum output current of up to 120A. It is also able to handle high surge input current up to 1.3kA and a high common-mode noise up to 110dB. Since it has an ultra-low profile of 0.75mm, it is well suited for applications requiring space efficiency.

Conclusion

The APT75DL120HJ is an ideal bridge rectifier for applications requiring both high efficiency and space efficiency. It is capable of handling high surge currents, wide common-mode range, and ultra-low profile. It is ideal for use in power supplies, DC motors, power adapters and other automotive applications where DC voltage is needed from an AC source.
