Diodes - Zener - Single

SMBG4748CE3/TR13 is a type of Zener diode from a popular family of SMBG 4700 Series. As a zener diode, it is a semiconductor device that allows current to flow in the forward direction, but when the voltage is larger than the zener breakdown voltage, the zener diode will go into the breakdown, then allowing current to flow in the reverse direction. This is a general overview of the SMBG4748CE3/TR13, it’s application field and working principle. The breakdown voltage of the SMBG4748CE3/TR13 is 4.7V. It is also suitable for use in infrequently operated inductive switchers, clamping applications, steering circuits and avalanche stabilization applications. With a compact TO-220F, 2-pin package, the SMBG 4748CE3/TR13 features low forward voltage drop and reverse leakage. Additionally, its maximum power dissipation is 0.4W, thus making this diode a popular choice for discrete devices, including diodes and transistors. SMBG4748CE3/TR13 has a number of important applications. It is used to provide protection against surges, and it is also used to keep the voltage on the battery terminals between a certain range. It is also used in computer power supplies and battery chargers, where it helps regulate the voltage in the system. It is also used in various electronic circuits, as it is suitable for clamping and steering applications, as well as avalanche stabilization. The working principle of SMBG4748CE3/TR13 is based on the principle of rectification. When the voltage on the anode is more than the reverse breakdown voltage of the diode, current flows from the anode to the cathode. In this state, the diode will conduct current and the voltage on the cathode will be less than the voltage on the anode. The current will then be limited only by the internal resistance of the diode. When the voltage is reversed, the current cannot flow in the forward direction. This prevents the reverse leakage of the diode, thus providing a stable current path. SMBG4748CE3/TR13 is an ideal choice for applications that require a low breakdown voltage, moderate current handling capabilities, and low forward voltage drop and reverse leakage. The small size of its package makes it suitable for use in various tight spots. As a Zener diode, it is suitable for use in a variety of circuits, and its ability to limit current in the reverse direction makes it a reliable component that can provide a stable current path.
