SMPZ3919B-M3/84A

SMPZ3919B-M3/84A is a Zener diode, which is a type of diode that contains a particular type of junction that is able to function under reverse biasing and that can regulate the voltage by redirecting the flow of current. It is intended for use in applications that require electrical isolation, such as overvoltage and reverse polarity protection, as well as rectification and supply regulation.

The SMPZ3919B-M3/84A is an efficient, low voltage Zener diode designed with a Schottky barrier on its anode, as well as a zener-specific region that maintains breakdown voltages when reverse-biasing is applied. This combination of elements allows the diode to maintain a stable voltage under a range of circumstances, allowing the diode to serve as a highly accurate and reliable voltage source.

The working principle of the SMPZ3919B-M3/84A is based on the principle of reverse breakdown. When the voltages applied to the diode exceed a certain level (known as the Zener voltage), the diode breaks down and a fraction of the current passing through the diode is redirected to the cathode. This behavior occurs at a steady, predictable level and is used to regulate the voltage applied to the diode.

The SMPZ3919B-M3/84A is designed for use in a variety of applications, such as voltage regulation in power supplies, voltage-clamping of high-amplitude surges, overvoltage and reverse polarity protection, and other high-precision applications requiring the maintenance of stable voltages. The diode is also well-suited for use in Pulse-Width-Modulated (PWM) circuits, where its ability to stabilize and limit the voltage coming through is vital.

As a reliable and efficient device, the SMPZ3919B-M3/84A is an ideal choice for applications requiring voltage stability, reverse polarity protection, and high-precision regulation. Its Schottky barrier design and Zener region construction offer superior electrical isolation and a highly accurate and stable source of voltage, making the diode well-suited for applications where accuracy and reliability are a priority.
