SMBJ5339A/TR13

The SMBJ5339A/TR13 is a single Zener diode available from ON Semiconductor. It is mainly used to provide voltage regulation or protection from voltage spikes. The SMBJ5339A/TR13 has a variety of applications, including battery protection, protection from overvoltage, power supplies, TVS protection, and ESD protection.

The SMBJ5339A/TR13 is a PN junction diode that consists of two semi-conductors with differing doping levels. The two semiconductors are separated by a thin layer of non-conductive material, which creates a high resistance junction. The resulting barrier allows the device to be used as a voltage regulator or protection device.

The SMBJ5339A/TR13 is designed to regulate the voltage at a specific level, regardless of the current or voltage coming through it. The voltage regulation is achieved through a Zener breakdown phenomenon. This occurs when an excessive voltage is applied to the diode, causing electrons to tunnel across the barrier. The number of electrons that tunnel depends on the amount of voltage applied; the higher the voltage, the greater the number of electrons that tunnel. This creates a current that is proportional to the amount of voltage applied. The device uses this current to regulate the output voltage of the device to a predetermined value.

The SMBJ5339A/TR13 is also designed to provide protection from voltage spikes. By clamping the voltage at a predetermined value, the device prevents any further increase in the voltage. This can help protect sensitive components from being damaged by a sudden surge in voltage. In addition, since the device is a PN junction diode, the device has a rectifying effect that can be used to provide protection from common-mode and transient ESD events.

The SMBJ5339A/TR13 is a reliable and stable device capable of providing a wide range of voltage regulation and protection from over-voltage or transient events. It is a great choice for applications that need to regulate voltage or provide protection from voltage spikes. It is an ideal choice for applications such as battery protection, power supplies, TVS protection, and ESD protection.
