SMBG5379C/TR13 is a single Zener diode device made of gallium arsenide and silicon substrate materials. It features maximum functional frequency up to 600MHz and large junction capacitance up to 3.9pF. This device is primarily used in many consumer electronics applications ranging from cell phones to DVD players.

The SMBG5379C/TR13 is a three terminal device which is typically used to provide overvoltage protection in electronic equipment when exposed to large voltage fluctuations. It performs this function by regulating the output voltage to a predetermined level when the input voltage exceeds a certain threshold. This protects the device from overvoltage damage and reduces the power supply design complexity. The operating voltage is between -2V and +25V.

The working principle of the SMBG5379C/TR13 is fairly straightforward. When the input voltage exceeds a certain threshold, the zener junction begins to conduct current and the voltage is clamped at the breakdown voltage of the zener diode. This can be achieved by connecting the anode and cathode of the diode directly to the input and output voltage source, respectively. When the input voltage is below the breakdown voltage, however, the voltage remains constant and no current flows. This allows the device to be used in applications that require a stable supply voltage.

One of the most common applications for the SMBG5379C/TR13 is providing overvoltage protection in cell phone charger circuits. This is generally achieved by connecting the anode of the diode to the power supply and the cathode to the ground. When the line voltage exceeds the breakdown voltage of the zener diode, the device will start to conduct current and will limit the output voltage to its rated breakdown voltage. This prevents the charger circuit from being damaged due to overvoltage. Other applications for this device include providing overvoltage protection to DVD players, digital television receivers, and smart cards.

In addition to providing overvoltage protection in electronics applications, the SMBG5379C/TR13 can also be used as a voltage reference in many systems. It can be used to set the reference voltage for an amplifier circuit or to supply a stable reference voltage for other circuitry. The voltage reference feature of this device is one of its most versatile assets. It can even be used in proximity detectors and other applications where a stable reference voltage is needed.

The SMBG5379C/TR13 is a great choice for many applications where a stable reliable voltage reference is required. Its high frequency operation, small size, and low power consumption make it an ideal choice for a wide range of applications. Its ability to provide overvoltage protection and act as a voltage reference makes it an invaluable asset when it comes to design and implementation of any type of electronic equipment.
