SMBJ4740A/TR13

The SMBJ4740A/TR13 is a Zener diode suitable for applications where transient suppression or overvoltage protection is needed. It comes with a maximum 1.5 watts of power dissipation and 5.1 volts of maximum reverse voltage. It has fast switching times with low dynamic impedance, making it a great choice for a range of circuit protection applications.The exact functionality of the SMBJ4740A/TR13 is that it acts as a Zener diode. A Zener diode is a special type of diode where the junction of the diode is reversed biased and a Zener breakdown occurs. When this breakdown occurs, the diode will break down and allow current to flow in both directions, providing energy to the circuit.The power rating and reverse voltage of the SMBJ4740A/TR13 make it suitable for a range of applications. For example, it can be used in applications such as AC/DC switching, DC/DC converters, and DC power supplies. It can also be used in circuit protection applications such as inrush current limiting and overvoltage protection.The SMBJ4740A/TR13 is available in a wide range of package and lead styles to suit various PCB designs. Its terminals are suitable for standard and J-lead mounting. It also comes with a 20 mA maximum reverse current and a 6 ω maximum dynamic impedance for effective protection of supply lines and other components in the circuit.Overall, the SMBJ4740A/TR13 is a great choice for a wide range of applications requiring fast, reliable and low-voltage protection. Its power rating, reverse voltage and fast switching times make it suitable for a range of applications and its wide range of packages and lead styles make it suitable for many PCB designs.
