The 1SMA4757HR3G is a single Zener diode that can be used in a variety of applications. It has a wide forward voltage range and a moderate reverse voltage range, making it ideal for a variety of applications, including voltage regulation, load balancing, and overvoltage protection.Its most common applications are in consumer electronics, automotive, aerospace, computing and telecommunications.

Working Principle

The 1SMA4757HR3G Zener diode works on a very simple principle. Its reverse current (Izk) is determined by the value of the voltage applied to its anode (Vzk). When the applied voltage rises above the Zener voltage, the Zener diode enters breakdown mode and the reverse current increases. The reverse current acts as a stabilizing current and ensures that the voltage remains close to the Zener voltage.

In addition, the device is also capable of regulating a higher voltage than the rated Zener voltage, up to a certain surge rating. This makes it well-suited to applications where a higher regulated voltage is needed. The device can also be used in a reverse connection; in this case, it will limit the reverse current flow through the diode.
