SMBG4729E3/TR13

Diodes - Zener - Single

The SMBG4729E3/TR13 is a single diode with a unique function and power supply feature. It is a diode that is able to provide short circuit protection up to 140V, while still being able to provide an output voltage of 3.3V. This diode is especially useful in applications that require a reliable and efficient alternative to linear regulators.

Application Field

The SMBG4729E3/TR13 is typically used as a voltage regulator in power supplies. It can be used to provide a steady output voltage with very low power loss, while still providing short circuit protection up to 140V. In addition, the diode also provides low noise operation, making it suitable for use in noise sensitive applications such as audio amplifiers and oscilloscopes.

The device can also be used for a wide range of other applications, including for rectification, voltage clamping, and over-voltage and current protection. The diode is also commonly used in automotive and aerospace applications, due to its high reliability and stable output voltage.

Working Principle

The SMBG4729E3/TR13 works by relying on the Zener voltage breakdown effect in diodes. When the voltage across the diode reaches the Zener voltage breakdown threshold, it will start to conduct electricity in the reverse direction. This causes a current to flow through the diode in the opposite direction, which creates a voltage drop across the diode and keeps the output voltage steady.

The device can also be used to limit the maximum output voltage of a power supply, by connecting the diode in series with the power supply. When the voltage across the diode reaches the Zener voltage breakdown threshold, it will start to conduct in the reverse direction, which will divert some of the power supply current away, limiting the output voltage.
