The SMBJ5348BE3/TR13 is a single Zener diode from the Diodes range of products. This diode is designed to regulate the voltage in an electrical circuit by preventing current flow above a given threshold. The diode is ideal for applications such as voltage regulators, voltage reference sources and clamping circuits.

The SMBJ5348BE3/TR13 is a small, low-cost device consisting of an anode, a cathode and a Zener region between them. It has no gate, meaning that it does not require any additional external control or activation. This makes it ideal for low-voltage, low-current applications.

The diode is able to withstand high temperatures, up to 175°C. It also has a high reverse voltage rating of 5.3V, making it suitable for a wide range of applications. This means that the diode can be used in a variety of circuits with varying voltages, allowing for a great deal of flexibility in design.

The SMBJ5348BE3/TR13 is typically used in voltage regulation circuits, clamping circuits and voltage reference sources. In voltage regulation circuits, the diode is used to ensure that a voltage will not exceed a certain level. Clamping circuits use the diode to limit the peak voltage in a power supply, while voltage reference sources use the diode to provide a stable voltage reference. In all of these applications, the SMBJ5348BE3/TR13 provides reliable and consistent performance.

The operation of the diode starts when the voltage across it, known as the reverse voltage, becomes greater than the Zener voltage. At this point, the diode begins to conduct current and the voltage across it is held at the Zener voltage, regardless of the voltage applied to it. This ensures that the voltage across the diode remains constant, preventing any overshoot or undershoot.

The Zener breakdown occurs when the electric field due to an applied reverse voltage exceeds the breakdown strength of the depleted semiconductor layer. This causes current to flow through the diode, allowing it to regulate the voltage as described above.

The SMBJ5348BE3/TR13 is a versatile, low-cost diode that can be used in a wide range of applications. It is suitable for use in circuits with varying voltages and temperatures, making it an excellent choice for even the most demanding applications. The diode is easy to use, reliable and provides consistent performance, making it an ideal choice for any project.
