TVS – Diodes are a type of semiconductor device that is designed to protect sensitive electronic components from large-scale electrical transients. They are used to protect power supplies and microcontrollers, as well as all manner of other sensitive electronic devices. The PACDN1404CG is a popular and reliable TVS-Diode, which has various applications and a straightforward working principle.

The PACDN1404CG is a Uni-Directional Transient Voltage Suppressor (TVS) diode. It is also a low-capacitance technology, which makes it suitable for applications that require a low total capacitance from the protection circuit. It is a uni-directional diode, meaning that it will only protect circuits from electrical transients flowing in one direction. This makes it ideal for applications such as over-voltage, reverse battery, and AC line faults, where pollution control and ESD protection are also important factors.

The main application for the PACDN1404CG is protection of electronic components from electrical transients such as electrostatic discharge, EFT, surge, over-voltage, etc. It is used to protect power supplies, microcontrollers, sensitive radio frequency (RF) components, and other sensitive electronic devices.

The working principle of the PACDN1404CG is based on the avalanche breakdown effect. This is a process where a small reverse voltage applied to the diode is amplified rapidly and causes the diode to enter into a conductive state. This allows the current to flow through the diode and the excess voltage is dissipated as heat. This phenomenon can also be used to protect the circuit form damaging transients.

In the case of the PACDN1404CG, the device has a breakdown voltage of 14V and a clamping voltage of 6.1V. This means that when transients of more than 14V are applied to the circuit, the diode enters into a conductive state and limits the voltage to 6.1V before dissipating the remaining energy as heat. This protects the sensitive components from most damaging transients.

The PACDN1404CG has a variety of applications in the protection circuits of power supplies, microcontrollers, and other sensitive electronic devices. It can also be used in pollution control and ESD protection circuits. Its low capacitance makes it suitable for applications that require a low total capacitance, and its uni-directional nature makes it ideal for applications that require protection from transients flowing in one direction. The PACDN1404CG is a reliable device with straightforward working principle.
