Diodes are electronic components with two main purposes: to allow current to flow in only one direction and to regulate or restrict the flow of current within a circuit. Zener diodes are a type of diode that serve the purpose of protecting electronic components from overloads. The SMBJ5347C/TR13, simplevone of single junctions, is one example of a Zener diode. This diode has a specific breakdown voltage, or reverse voltage rating, allowing it to function in a variety of applications.

Breakdown Voltage

The primary functionality of all Zener diodes, including the SMBJ5347C/TR13, is that they provide a stable voltage by clamping the voltage of a circuit. This is accomplished by it having a breakdown voltage, which is when the current passing through the diode reverses and flows through in the opposite direction. The SMBJ5347C/TR13 has a breakdown voltage of 5.6V, meaning that is the voltage at which current will begin to flow in the opposite direction. This single junction Zener diode is able to provide a wide range of reverse voltage ability for circuits, because it has a voltage drop that only increases with higher current.

Applications

Due to the SMBJ5347/TR13’s low breakdown voltage, it is used in many different applications. One common application is protection of circuits from voltage surges. This is particularly useful for high-power circuits, as Zener diodes can help protect those circuits from damage due to accidental overloads. The SMBJ5347C/TR13 is also often used in voltage dividers and voltage reference circuits, as it’s low breakdown voltage allows it to control exactly how much voltage can pass through a given circuit. This is especially useful for circuits that need to be carefully regulated.

Working Principle

The working principle of Zener diodes, including the SMBJ5347C/TR13, is actually quite simple. When no current is flowing through the diode, it acts as a conductor, allowing current to pass through it. This is the same as any other diode. However, when the forward voltage of the circuit exceeds the breakdown voltage of the diode, current will then flow in the opposite direction. This sudden shift in current direction causes the voltage across the diode and the circuit to stabilize, protecting the circuit from any further voltage increases.

Conclusion

Overall, the SMBJ5347C/TR13 is a Zener diode that is used in many different applications. Its low breakdown voltage allows it to regulate voltage in circuits and protect them from electrical surges. The working principle of this diode and other Zener diodes is fairly straightforward: when the forward voltage exceeds the set breakdown value of the diode, current will flow in the opposite direction, creating a stable output voltage. By understanding its applications and working principles, it is easy to see why this diode is so important and beneficial in many different circuits.
