A diode is an electrical component with two terminals, one anode and one cathode, which allows electrical current to flow in one direction only. Zener diodes are special diodes that are designed to function correctly when the applied voltage becomes reversely biased. The SMBG5956AE3/TR13 is an example of a single zener diode, which has several distinct application fields as well as working principles.

This diode is chiefly used in voltage clamping, voltage regulation, and voltage spike protection. Its voltage clamping application involves limiting the voltage of the signal by allowing only a predetermined voltage level to pass through, while its voltage regulation application helps maintain a stable voltage level. As for voltage spike protection, the diode absorbs and dissipates the energy associated with an abrupt rise in voltage. The SMBG5956AE3/TR13 is also often utilized in energy storing and power supplies, such as LED drivers.

The diode’s working principle is based on the Zener effect, which is a phenomenon whereby a diode’s junction breakdown occurs at a particular reverse voltage, making it applicable in the regulation and stability of voltage. When the reverse voltage reaches its threshold, current will start to travel in the reverse direction. This current flow is called the Zener breakdown current, which gets regulated by the negative feedback of the voltage drop. As the voltage reduces, the current is limited by the resistor connected in series with the diode, which in turn causes a decrease in the Zener breakdown current.

Moreover, the SMBG5956AE3/TR13 has a maximum power dissipation rating of 0.5W and a maximum operating temperature of +85°C. Its power dissipation rating indicates that, in a circuit, it can take no more than 0.5W of electrical power to achieve its maximum efficiency. In addition, its maximum operating temperature means that it is suitable for operating in a relatively warm environment.

In comparison to traditional diodes, Zener diodes have a much lower reverse breakdown voltage, making them ideal for operations requiring precise voltage configurations. The SMBG5956AE3/TR13, in particular, is a single zener diode with a wide range of application fields and a clear working principle.
