SMBJ4753/TR13: Application Field and Working Principle

The SMBJ4753/TR13 diode is a single, low-power, low-voltage Zener diode. It is designed to provide a highly regulated voltage source, offering protection against reverse-bias conditions, as well as overvoltage transients. It is also used to protect transformer circuits from overvoltage.

Application Field:The SMBJ4753/TR13 diode is ideal for use in industrial and consumer applications including voltage regulator circuits, data acquisition systems, motor control, telecommunication, and power supplies. Its low forward voltage and low power consumption make it suitable for energy-saving applications and multiple-ordered supply voltages.

Working Principle:The working principle of the SMBJ4753/TR13 is based on the Zener effect. In normal operation, the Zener diode behaves like a normal diode, and current flows through it from the anode to the cathode. When the voltage exceeds the zener breakdown voltage, or Vz, the diode is reverse-biased and current does not flow. The diode then becomes an overvoltage clamp, allowing the voltage to be regulated at a predetermined level. In this way, the diode prevents damage to the device from overvoltage transients.

The SMBJ4753/TR13 is constructed using a planar epitaxial design, which allows it to operate in a wide temperature range, and it is also RoHS compliant. The device offers a fast response time and very low leakage current. It is available in a TO-220 package, making it well-suited for mounting on heat sinks.

In summary, the SMBJ4753/TR13 diode is a single, low-power, low-voltage Zener diode that is designed to provide a highly regulated voltage source, offering protection against overvoltage transients and reverse-bias conditions. It is ideal for use in a variety of applications, including voltage regulator circuits, data acquisition systems, motor control, telecommunication, and power supplies. The device offers a fast response time and very low leakage current, making it an excellent choice for energy-saving applications.
