SMBG4750/TR13

Diodes - Zener - Single consist of an active region sandwiched between p-type (positive) and n-type (negative) semiconductor regions. While the operation of p-n junction diodes can be modeled in a simple way, the SMBG4750/TR13 requires a far more detailed model and understanding. This article will cover the application field and working principle of the SMBG4750/TR13.

Application Field of the SMBG4750/TR13

The application field of the SMBG4750/TR13 is best described in terms of voltage, current, and power. The SMBG4750/TR13 is designed to work in a wide variety of applications, including stabilizing circuits, voltage regulators, level shifters, and power supplies. A typical application of the SMBG4750/TR13 is to limit the voltage across a load to a safe and stable value.

Working Principle of the SMBG4750/TR13

The SMBG4750/TR13 works on the principle of a reverse biased p-n junction diode. When a reverse bias voltage is applied, the diode starts to conduct, and the current across the diode increases until it reaches a certain breakdown voltage, or Zener voltage. At this point, the current through the diode remains relatively constant, allowing it to act as a voltage regulator. This breakdown voltage of the SMBG4750/TR13 is typically 5.1V.

The SMBG4750/TR13 also features a wide power dissipation range and high surge current capability. This allows it to be used in a variety of applications, from low-power, low-voltage circuits, to high-power, high-voltage circuits. In addition, the SMBG4750/TR13 has low reverse leakage current, which makes it ideal for low-power circuits.

Conclusion

The SMBG4750/TR13 is a versatile Zener diode, designed to work in a wide variety of applications. Its breakdown voltage of 5.1V allows it to be used as a voltage regulator, while its wide power dissipation range and high surge current capability make it ideal for a variety of applications. Finally, its low reverse leakage current makes it ideal for low-power circuits.
