Diodes are semiconductor components with the ability to control the flow of electricity. Rectifiers are specialized diodes that are used to convert alternating current (AC) to direct current (DC). Arrays are groups of semiconductors that are connected together to produce a particular function such as switching or providing an output. The DD175N30KHPSA1 is an example of a diode rectifier array designed to provide a level of protection against surges or transient voltage in systems such as computers or other electronic equipment.

Application Field

The DD175N30KHPSA1 is a transient voltage surge suppressor (TVSS) designed for use in industrial, commercial, and residential applications. The device is used to protect electrical systems from damage caused by transient electrical surges. Examples of applications for this device include:

• Computers
• LCD/Plasma TVs
• Industrial machines
• Electronic equipment
• Communications systems

The device is designed to protect against transient over-voltages, lightning strikes, and power harmonics. It can be used in AC mains applications, DC applications, single-phase and three-phase systems, and in many other environments where electrical transients may occur.

Working Principle

The DD175N30KHPSA1 is a diode rectifier array that utilizes TVS technology. The device is constructed from two identical rectifier arrays connected in a "figure 8" fashion, with each array being composed of six high-efficiency fast recovery diodes. The anodes of each array are connected together and the cathodes are connected together. The anode of one array is connected to the cathode of the other array. This provides an integrated protection path for the electrical circuit.

When a transient voltage surge occurs, the diodes in the array will conduct electricity, allowing the excess high-voltage current to be diverted away from the protected circuit. The diodes have a fast response time which is important in protecting against transient voltage surges. As the voltage decreases below a predetermined threshold, the diodes will stop conducting current, preventing the surge from damaging the protected circuit.

The DD175N30KHPSA1 diode rectifier array is designed for protection against transient voltage surges up to 30 kV max. It is intended for use in AC mains applications and offers a low-cost solution for protecting electrical equipment from damage caused by transient electrical surges.
