TVS, which stands for Transient Voltage Suppressor, is an electronic device that protects sensitive electronic components from voltage spikes due to lightning, static discharges, and electro-magnetic discharges. It works based on the principle of surge dissipation, which is where when a surge of current is applied to the TVS diode, the diode will clamp and limit the maximum voltage from reaching the protected electronics. This saves the protected components from damage, which in turn, extends the products life.

The SMAJ85AHE3/5A, produced by ON Semiconductor, is a series of TVS Diodes that provide superior ESD, EFT, and surge protection for sensitive devices. This device can handle up to 5 kilovolts (5kV) of electrostatic discharge, 5 amperes of electrical fast transients, and 5 amp surges. The SMAJ85AHE3/5A is able to remain stable under AC and DC conditions as well.

The SMAJ85AHE3/5A finds its use in a variety of applications where protection against electrical surges is necessary. Some of these applications include personal computers, computer peripherals, servers, data networks, mobile phones, home electronics, industrial machinery, and consumer electronics. The device is engineered to have an extremely low capacitance on the output side, protecting powered circuit systems from possible ESD damage.

SMAJ85AHE3/5A devices are designed with the junction of two diode circuits. This junction found at the negative side of the device works by providing a low-impedance path when the surge voltage exceeds the breakdown level of the device. This junction also provides a low capacitance path to ground, which prevents the voltage from doubling.

These diodes are designed with a low capacitance on the output side that protects powered circuit systems from possible ESD damage. The SMAJ85AHE3/5A also has a fast response time of 1ns at 1/2 voltage levels. This allows the device to respond quickly to incoming surges of current, thus protecting the load from further damage.

When it comes to installation, the SMAJ85AHE3/5A can be soldered directly into the circuit it is protecting. This makes the installation process quick and easy, allowing engineers to be able to get their equipment up and running in no time.

In summary, the SMAJ85AHE3/5A device from ON Semiconductor is a series of TVS Diodes that provides superior ESD, EFT, and surge protection for sensitive devices in various applications. The device can handle up to 5 kilovolts of electrostatic discharge, 5 amperes of electrical fast transients, and 5 amp surge currents. It is also designed with a low capacitance output, a fast response time, and is easy to install. Consequently, the SMAJ85AHE3/5A offers engineers a reliable way to protect their circuits against sudden voltage surges.
