SMZJ3798AHE3/5B application field and working principle

SMZJ3798AHE3/5B is a Zener diode, which belongs to the single devices category. It has a wide range of applicability in electronics, including but not limited to devices that require absolute voltage stabilization, noise filters, and the generation of a negative bias voltage. It can also be used to limit maximum voltage at an output in order to protect other components.

The working principle of a Zener diode is based on the fact that when a reverse-biased non-conductivep-n junction experience a voltage above the Zener breakdown voltage, it allows a large current to flow in the reverse direction. This phenomenon is known as Zener breakdown, or avalanche breakdown. The Zener diode behaves very much like an ideal voltage source, meaning it will keep the output voltage stable even if the input varies; for this reason, it is often used to produce a precise output voltage.

Another application of Zener diodes is protection from extreme voltage, such as surge protection. When a surge is present, a Zener diode will conduct current beyond the device\'s breakdown voltage and dissipate the extra energy. This will prevent any possible damage to connected devices, due to the excessive voltage that may arise during a power surge, allowing the duties in a system of multiple components to remain unchanged.

As for circuit design, SMZJ3798AHE3/5B can be used in a variety of ways, depending on its type. While the general practice is to connect it in series, there are also other approaches. For instance, the Zener diode can be incorporated in the form of voltage dividers, or it can be configured as a reference voltage source, in order to control the further functioning of the circuit and provide regulation where required.

SMZJ3798AHE3/5B is a good choice for circuit designers who are looking for a device that provides practical voltage regulation, as well as protects against large voltage surges. Compared to other types of diodes, the Zener has a maximum breakdown voltage which is much higher, making it suitable for a variety of applications.
