TVS - Diodes: 5KP78CAE3/TR13 application field and working principle

TVS-diodes, or Transient Voltage Suppressor Diodes, are available in a wide range of sizes and voltages and serve a variety of protection purposes. They are used to suppress large voltage transients on a line or signal conductor, protect against against ESD (electrostatic discharge), and protect against high energy line inductive transients in electronic circuits. The 5KP78CAE3/TR13 is a type of TVS diode that specifically provides overvoltage and ESD protection.

Application Field of the 5KP78CAE3/TR13

The 5KP78CAE3/TR13 is designed for use in a variety of applications including automotive, consumer electronic, telecom and industrial. It is suitable for ESD protection of data and lines such as I2C, I3C, USB 2.0/3.0, HDMI, DVI and LVDS. It is also suitable for overvoltage protection of data and lines such as UART, CAN, GPIO, and differential signals.

Working Principle of the 5KP78CAE3/TR13

The 5KP78CAE3/TR13 works by protecting against voltage transients generated by electrostatic discharges or inductive high-energy transients. It is built with PN junction diodes that are designed to lower the breakdown voltage when there is a short circuit or a high current situation. In the presence of an overvoltage, the PN junction diodes will start to conduct and absorb the extra energy, thus preventing further damage to the surrounding electronic components. There is also a peak pulse current rating, which determines the maximum current that the diode can withstand without permanent damage.

When there is a static discharge, the TVS diode will create a low-resistance path that will absorb the high voltage and dissipate it. This prevents the overvoltage from reaching the input of the system and potentially damaging the equipment. This is one of the most important roles of the 5KP78CAE3/TR13, as it can provide the necessary protection against ESD transients.

Conclusion

The 5KP78CAE3/TR13 is a type of TVS diode that is designed for use in a variety of applications and offers protection against ESD and overvoltage transients. It works by providing a low-resistance path that will absorb the high voltage and dissipate it, thus preventing further damage to the surrounding electronic components. It is suitable for protecting against static discharges and is an important component of any system that needs voltage protection.
