TVS - Diodes

A Transient Voltage Suppressor Diode, or TVS Diode, is a three-terminal semiconductor device designed to protect sensitive electronic components from electrical overstress, including lightning, from both surges and electrostatic discharge (ESD). TVS Diodes often take the form of a Zener diode, and also can include more complex circuitry such as surface mount diodes, avalanche diodes, or components with positive temperature coefficients (PTCs). The high peak pulse power capabilities of TVS devices ensure that the connected ICs are protected from damaging power surges.

TV04A111J-G is an example of a TVS diode. It is a unidirectional uni-polar device that is specifically designed to protect electronics from over-voltage transients. It has a breakdown voltage of 14 volts and it is capable of dissipating power up to 1.5 watts. It has a reverse leakage current of 2.0 nA at 8V and a clamping voltage of 29V, making it suitable for use in a wide range of applications.

The TV04A111J-G is designed to be used in the fields of telecommunications, industrial control, automotive, consumer electronics, and in many other applications that require a reliable means of protecting sensitive circuits from potentially damaging transients. It is typically used in applications with high transient levels, such as AC power lines, lightning, and ESD. It can also be used in critical components that require a higher degree of protection, such as those used in automotive systems.

The working principle of the TV04A111J-G is relatively simple. When exposed to an over-voltage transient, the diode begins to conduct as soon as the voltage exceeds a certain predetermined level, known as the breakdown voltage. The diode conducts until the reverse voltage drops below this level, at which point it stops conducting. It effectively protects the connected ICs by safely diverting the excess transient energy away from the ICs and safely dissipating it as heat.

The TV04A111J-G features a ceramic body which allows the device to dissipate heat effectively. It is also constructed with an extra-large die which allows it to store more energy and dissipate it faster than many traditional TVS diodes. This feature is particularly advantageous in applications that require faster response and higher levels of protection against transient voltage spikes.

In summary, the TV04A111J-G TVS Diode is an invaluable device that is designed to protect electronics from potentially damaging voltage transients. Its high peak pulse power capabilities and its large die size offer reliable protection for a wide range of applications. Its ceramic body allows it to effectively dissipate the energy of transient voltage surges, providing a safe and reliable means of protecting sensitive electronic components.
