Diodes, rectifiers, and arrays are frequent components used in a wide range of electrical engineering applications. The DAP222MT2L is a Manually Operated Rectifier Array, specially designed for filtering, load balancing, and other applications. In this article, we will discuss the application field of the DAP222MT2L, as well as its working principles.

Application field of the DAP222MT2L
The DAP222MT2L is a basic two-channel rectifier array. It is often used in electronic applications requiring a two-channel rectifier, such as voltage regulation and reverse current prevention, as well as more specialized applications, such as electric current smoothing, for example. It is also used in systems where redundancy or low voltage is a requirement. In addition, the DAP222MT2L has been designed to work in harsh environments, where wide operating temperatures are required (up to 70 °C). Its rigid yet small package is also advantageous, making it suitable for low-profile and space-constrained designs.

Working Principles
The DAP222MT2L consists of two integral SCRs that are triggered independently. When a voltage is applied to the DAP222MT2L’s inputs, the SCRs draw current in the reverse direction, so forming a rectified current of alternating polarity within the channel. This process is known as Rectification. The rectified current, which is initially discontinuous, is then filtered through the network of components within the DAP222MT2L. This process smoothens the current, transforming it into a continuous DC output.

Both channels are reverse coupled, to ensure that current does not leak between the two. This implies that a certain input voltage needs to exceed the reverse breakover voltage of both channels before current starts to flow, since the two channels are connected in parallel and behave independently.

The DAP222MT2L provides a fast switching speed (tAV = 40ns) and is immune to noise spikes. Its low on resistance maximizes the efficiency of any system incorporating the device, since less power is wasted in dissipation.

In conclusion, the DAP222MT2L rectifier array is an invaluable tool in a wide range of electronic circuits and applications, ensuring fast switching speed and noise immunity, while providing low power dissipation in the process.
