Diodes - Zener - Single

The SMBJ5955AE3/TR13 is a Zener diode with a voltage capability of 5.6V. It has various applications and is particularly useful in environments with high humidity. Its main purpose is to regulate the voltage in a circuit by allowing current to flow in one direction and blocking it in the opposite direction.

A Zener diode is an electronic device that operates under the principle of reverse-biased breakdown. It consists of a reverse biased p-n junction, where the junction is made of silicon. When the diode is reverse biased, it has a very low resistance, allowing current to flow through it. As the applied voltage increases, the electric field across the junction increases and eventually exceeds the breakdown voltage Vz. This causes the electrons to recombine momentarily, resulting in a large current. This current is then regulated to the original voltage. This property makes it useful for voltage regulation or clamper circuits.

The SMBJ5955AE3/TR13 is an ideal diode for high humidity applications, with high thermal resistance and a junction temperature range of -55℃ to +150℃. It contains high-grade epoxy fill and is RoHS compliant. The voltage regulation range is between 5V and 5.6V, making it suitable for a variety of applications.

The main applications of this diode are in voltage regulation and clamps, overvoltage protection circuit, voltage clamping, ESD protection, and surge suppression circuits. It is also used in automotive and industrial applications such as automotive electronics, electric and hybrid vehicle charging circuits.

The working principle of a SMBJ5955AE3/TR13 is the same as any other zener diode, such as the common 1N4733A. A zener diode rectifies the input voltage and regulates it under the breakdown voltage. It does this by allowing current to flow in one direction and blocking it in the opposite direction. When the voltage reaches the breakdown voltage, it stopped flowing, and the output voltage is regulated at the breakdown voltage.

Zener diodes are an essential part of electronics, as they provide a stable and controlled output voltage across various application areas. The SMBJ5955AE3/TR13 is a popular zener diode due to its high voltage capabilities and its ability to withstand high humidity environments. It is used in a wide range of automotive and industrial applications, making it a critical component for a variety of technological advancements.
