TVS – Diodes are most commonly used for the purpose of protecting sensitive electronics equipment and other components from various over-voltage and electrical transients. The PACDN1408CG is especially designed to provide a high level of electrical protection and enable designers to gain maximal safety. It is an integrated solution of PAD (Packaged Array Diode) devices which works in the following ways:

The PACDN1408CG is a three-terminal diode consisting of two anode and one cathode terminal. It works as an asymmetrical voltage dependent switch which is triggered by a voltage threshold which is set according to the breakdown level of the ACDN1408CG. This threshold can be adjusted via internal integration circuitry. The threshold of this diode can be preset over a wide range between 5V-330V and the breakdown voltage is typically in the range of 400V-430V.

When the voltage exceeds the voltage threshold, the PAD devices are triggered and the electrical current is diverted asymmetrically to the anode terminal. This is done in a controlled manner and provides protection against transient over-voltage scenarios. As soon as the voltage falls below the threshold, the diode turns off and the electrical current is again allowed to flow through its normal path.

The PAD devices also make it possible to control the surge current of the diode by limiting the current to a maximum, which is adjustable. This enables the protection of sensitive systems, along with enhanced safety of any related circuits. The diode is constructed to be compatible with standard printed circuit boards.

The PACDN1408CG is used in multiple applications including the protection of IP communication networks, land-mobile radio systems, and computer systems. It can also be used for protecting a variety of automotive electronic systems and aerospace applications. It is well-suited for mains switching, AVSS, sensitivity and equipment host protection.

The PACDN1408CG makes it possible to protect digital devices from ESD events and surge transients, eliminating the need for bulky, expensive protection components. It also ensures an increase in the durability of the protected equipment. The diode also has low device capacitance and clamping voltage, which helps in minimizing the switching transients and providing an efficient ESD performance.

The PACDN1408CG offers a fast response time and superior transient over-voltage protection which is needed in applications where safety of systems is a must. It also offers the option to control the surge current and provides enhanced signal integrity and data recovery.

In conclusion, the PACDN1408CG is a three-terminal diode which can be used for over voltage protection in various applications. It is most effective in protecting digital devices from ESD events and surge transients, and has the ability to limit the current to a maximum. It is highly reliable and contributes majorly to enhanced signal integrity and data recovery.
