TVS – Diodes are an integral part of circuit protection. They are used to protect circuits from electrostatic discharge (ESD) and other overvoltage events. The device is based on an avalanche breakdown of a reverse biased junction of the diode. The SMAJP4KE39A-TP (hereinafter “TP”) is a surface-mount bidirectional diode with special bidirectional overvoltage protection characteristics. It offers fast and reliable over-voltage protection with an ultra low capacitance for both common mode and/or differential mode applications.

The TP is one of the most commonly used TVS diodes. It is designed to limit high levels of voltage spikes, transients, and surges. It has a peak pulse power rating of 500 watts. This makes it suitable for both consumer and industrial applications. The device also has a low capacitance of less than 0.5 pF which ensures it offers excellent signal integrity and high-speed transmission. The maximum operating voltage of the device is 600 volts and the breakdown voltage is 400 volts. The device also has an ESD protection rating of 15 kV.

The working principle of TP is based on the breakdown of the voltage across a reverse biased diode. When a voltage higher than the breakdown voltage is applied, an avalanche breakdown occurs and current begins to flow through the diode. This current is limited by the series resistors and the diode can absorb the voltage spike. The high voltage also creates a path to ground which dissipates the energy.

The TP can be used in a wide range of applications. It can be used for ESD protection of audio, video and data transmission lines. It is ideal for protecting a system from overvoltage events or voltage surges. It can also be used in computer and telecommunications equipment. Additionally, it can be used in automotive and industrial applications. It is a one stop shop for overvoltage protection solutions.

In summary, the SMAJP4KE39A-TP is a robust and reliable TVS diode designed for use in high speed differential and common mode applications. It is suitable for both consumer and industrial applications providing excellent ESD and overvoltage protection. The device’s ultra-low capacitance ensures great signal integrity while its low-power consumption and high-speed response make it a perfect choice for applications such as audio, video and data transmission lines. The TP can also be used to protect automotive and industrial equipment from overvoltage events and surges.
