Diodes - Zener - Single

The MMSZ5238BS-7 is a Single Zener diode, specifically designed for application fields where stability and accuracy are of the utmost importance. This particular device features a maximum average noise current of less than 50nA (10V-400V) over a wide range of operating temperatures (-55 to +150°C). It also offers an impressive 1% tolerance over its entire spectral range.

A Zener diode is a type of diode that allows current to reverse-bias through it, which limits the voltage across the diode to a maximum value when the required voltage exceeds the Zener voltage. The MMSZ5238BS-7 has a Zener voltage range of 4.3V to 370V, making it suitable for a variety of applications.

The MMSZ5238BS-7 is well suited for applications such as voltage reference, voltage clamping and protective circuits. These applications require the device to regulate voltage very accurately, even under changing ambient temperatures and low current levels. The Zener diode\'s ability to maintain a constant voltage level and low noise performance makes it the ideal choice for use in these types of applications.

One of the main advantages of the MMSZ5238BS-7 is its low noise performance, making it suitable for use in low noise applications such as medical devices and laboratory equipment. The diode is also RoHS compliant that can safely be used in hazardous voltage environments.

The working principle of the MMSZ5238BS-7 is based on the Zener breakdown mechanism. In this mechanism, when the applied voltage across the diode exceeds the Zener voltage, it activates an avalanche current, which allows current to flow in the reverse direction. This action, in turn, limits the voltage of the diode to a constant value.

The MMSZ5238BS-7 is an efficient and reliable diode for a wide range of applications. Its stability, accuracy and low noise performance make it the perfect choice for applications that require precision voltage regulation.
