Introduction

The SMBJ4763/TR13 is a Pb free (RoHS) compliant, single Zener diode, manufactured by ON Semiconductor. This diode is used for device protection and voltage regulation in applications requiring a nominal breakdown voltage of 13V. In addition, the SMBJ4763/TR13 has a maximum power rating of 500mW and a maximum DC reverse voltage of 14V.

Application Fields

The SMBJ4763/TR13 is used in a variety of applications where device protection is essential. This diode is often employed in power supplies, battery operated equipment, solar energy converters, and automotive applications.The SMBJ4763/TR13 Zener diode is specifically designed to provide stable voltage regulation. This diode is commonly used to protect transistors, diodes, and other sensitive components from high voltage conditions. By connecting the SMBJ4763/TR13 in parallel with the protected device, it acts as a voltage regulator, providing a constant regulated voltage to the protected device.

Mechanical Construction

The SMBJ4763/TR13 diode has a molded plastic case, with a matte finish, featuring the industry standard DO-214AC(SMB) shape. This case helps provide protection from transient voltage and electromagnetic interference. The dimensions of the SMBJ4763/TR13 are a length of 3.40mm, a width of 1.70mm, and a height of 1.25mm. Furthermore, this diode has a weight of 0.043g (1.5mg).

Working Principle

The SMBJ4763/TR13 is a single Zener diode. It consists of a p-n junction, which is designed to breakdown at a certain reverse voltage. When the reverse biased voltage across the diode exceeds the Zener voltage, the junction will allow a large reverse current to flow. This current flow is limited, since the Zener voltage will remain constant, regardless of the applied voltage. In conclusion, the SMBJ4763/TR13 is a Pb free (RoHS) compliant, single Zener diode, manufactured by ON Semiconductor. This diode is used for device protection and voltage regulation in applications requiring a nominal breakdown voltage of 13V, and has a maximum power rating of 500mW. The SMBJ4763/TR13 Zener diode is specifically designed to provide stable voltage regulation, and is often employed in power supplies, battery operated equipment, solar energy converters, and automotive applications.
