SMZJ3797AHE3/5B Datasheet/PDFDiodes - Zener - Single
The SMZJ3797AHE3/5B is a single zener diode, providing regulated voltage to circuit elements. These devices are widely used for their ability to both convert alternating current to direct current (AC/DC) power, and also provide a reference voltage source.
Application Field
The SMZJ3797AHE3/5B diode is a popular device in many industries and applications, both commercial and industrial. It\'s often used to stabilize and power circuits, as well as to provide a reference voltage for components. It is used in a variety of circuits, including power supplies, audio amplifiers, LED lighting systems, and in automotive and home electronics.
Working Principle
The SMZJ3797AHE3/5B is a silicon-based diode, typically operated with forward bias. This means that current flows from the anode to the cathode. When the forward voltage is applied, the device behaves as a resistor and limiting current is then passed through. When the voltage across the device exceeds the zener breakdown voltage, the current flows freely. This provides the stabilized voltage output.
As described earlier, the diode conducts with the application of a forward voltage and the voltage is regulated by an internal zener breakdown voltage. This breakdown voltage is fixed, which accounts for its precision in voltage control. The Zener diode is able to control the voltage as well because a certain amount of current is always required to maintain the zener breakdown voltage.
The SMZJ3797AHE3/5B is an ideal choice for power supplies, LED lighting systems, and home electronics. Its ability to provide a regulated voltage output, as well as a stable reference voltage makes it an excellent choice for modern electronics.
