Zener diodes are semiconductor devices that allow the current to flow in one direction while acting as an insulator when the current flows in the other direction. Zener diodes are widely used in various applications as they provide a stable flow of current, even in the presence of fluctuations in the voltage of the power source. This makes them ideal components for applications where a regulated and reliable current is needed for proper functioning.

An example of such an application is the MMBZ5239BS-7-F, a Zener diode array. This diode array is constructed by combining two Zener diodes in series and an AEC-Q101 qualified common cathodeline for voltage regulation. The MMBZ5239BS-7-F is a low cost and reliable solution for surge protection and overvoltage protection of sensitive electronic equipment.

The diode array can be used in various applications such as computer systems, home appliances, tablets, mobile phones, and industrial equipment. From a technical perspective, the MMBZ5239BS-7-F is a two-diode array arranged in a 2-pin SOD-123F package. This chip features a total on resistance (RON) of 0.58ohm, leakage current of 2µA, and a nominal reverse breakdown voltage (VZ) of 6V. The chip is also designed to handle a maximum power dissipation (PD) of 500µW.

When it comes to its working principle, the two Zener diodes have a large reverse voltage, which helps protect the device from over-voltage spikes. As a result, when the power supply voltage exceeds the predetermined breakdown voltage, the current is diverted through the diodes and thereby protecting the device from any harmful surges. On the other hand, when the power supply voltage is within the acceptable limits, the current remains unaffected, thus providing a stable flow of current.

In summary, the MMBZ5239BS-7-F is a reliable and cost effective solution for various applications where a stable current is required. It is a two-diode array with a low on resistance (RON) and a nominal breakdown voltage (VZ) of 6V. The diode array can be used for surge protection as well as for over-voltage protection of sensitive electronic equipment, making it a perfect choice for various applications such as computers, home appliances and industrial equipment.
