Diodes - Zener - Single, as the name suggests, are a kind of single Zener diodes designed for low voltage applications. The SMBG5384CE3/TR13 is a popular model in the range. It is a surface mount diode that exhibits high total capacitance, low maximum reverse voltage and a tight temperature coefficient.

The SMBG5384CE3/TR13 is typically used in switching regulators, TV tuners, electro-optical systems, power supplies, battery chargers, voltage automation supply systems and general rectification. It is suitable for both AC and DC applications.

The SMBG5384CE3/TR13 has a nominal breakdown voltage of 5.0V and a maximum current rating of 1mA. It has a power handling capacity of 500mW and a total capacitance of 510pF. The junction temperature rating is -55°C to +150°C, the thermal resistance is 16.4°C/W, and the maximum reverse leakage current is 1.0µA.

The working principle of the SMBG5384CE3/TR13 begins with the bi-directional flow of current. When the voltage across the diode is below the specified breakdown voltage, the diode will carry the same current in both directions. As the voltage rises, however, the current flows predominantly one way, allowing only a small amount of current to pass through in the other direction. When the reverse voltage reaches the Zener breakdown point, the diode will break down and allow a higher level of reverse current to pass. This process is known as Zener breakdown and is essential to the diode’s normal operation.

The SMBG5384CE3/TR13 is also capable of suppressing transients, protecting against transient spikes and clamping the output voltage if it exceeds a certain level. The diode is also capable of providing over-voltage protection, as it can limit the voltage output in a circuit.

In summary, the SMBG5384CE3/TR13 is a single zener diode designed for low voltage applications. It is capable of suppressing transients, protecting against transient spikes and clamping the output voltage if it exceeds a certain level. It is typically used in switching regulators, TV tuners, electro-optical systems, power supplies, battery chargers and voltage automation supply systems.
