Diodes - Zener - Single: SMBJ5371BE3/TR13 Application Field and Working Principle

The SMBJ5371BE3/TR13 is a single Zener diode, part of a larger category of semiconductors known as “diodes”. Diodes are the fundamental components of utilities and electronics, and come in a variety of shapes, sizes and functions. This article will illustrate the application field and the working principles behind the SMBJ5371BE3/TR13. First, let us examine its general features.

The SMBJ5371BE3/TR13 is a 0.5 watt Zener diode that operates with a voltage range of 5.1 to 200 Volts. It has a peak reverse current of 5 uA and a maximum power dissipation of 500 mW. It also includes a wide operating temperature range of -65 to +175 degrees Celsius. Its structure and physical size include a dual cathode, a single anode and a package size of DO-213AA.

The basic purpose of a Zener diode is to stop particle flow in one direction and allow it to move in the opposite direction when a certain voltage is applied. While this is a basic function, its particular application within the SMBJ5371BE3/TR13 results in what is known as “clamping” or “shunting” the voltage and current levels at the desired location. This behavior is what is typically referred to as “regulation” or “controlled impedance.”

The main application of the SMBJ5371BE3/TR13 is in voltage regulation and/or protection circuits. It is frequently used to protect sensitive equipment from power surges. It may also be used in the manufacture of integrated circuits to control the low-voltage supply for other transistors and other CMOS components within the device. Additionally, the SMBJ5371BE3/TR13 is used as a reference source in high-voltage circuits and can be combined with other Zener diodes to form a voltage divider.

The working principles of the SMBJ5371BE3/TR13 are based on what is known as the Zener effect. This effect is caused by a process in which electrons from the N component are injected into the P component of a diode at a certain voltage. This creates a region of high-concentration of majority carriers, which is referred to as a “depletion zone.”

When an external voltage is applied between the anode and cathode of the diode, the depletion zone widens, which decreases the current and voltage across the diode. Since the current is low and the majority carriers are not present, the Zener breakdown occurs. Because the majority carriers are not present, the flow of electrons across the threshold voltage is allowed.

The SMBJ5371BE3/TR13 creates a reverse current when the applied voltage becomes higher than the Zener breakdown voltage. This is referred to as “zener regulation” and provides a known and stable voltage for use in a variety of applications.

The SMBJ5371BE3/TR13 is used in a variety of applications in circuit protection, including power supplies, voltage tracks, voltage regulators, and pulse formers. The device’s features allow it to effectively control the voltage or current for a specific application. It is a great example of the versatility of semiconductors, with this single component providing a great deal of protection and control in a variety of devices.
