Introduction: SML4749-E3/61 is a single Zener diode, which is generally used for Zener breakdown applications. It is composed of an anode and a cathode, and its electrical characteristics are defined by a Zener voltage, a maximum Zener current, and a maximum dissipation power at an ambient temperature.

Application Field: SML4749-E3/61 is mainly used for voltage stabilization, voltage-limiting and clamping. It can be widely used in electronic circuits, such as power supplies, voltage regulator circuits, automobile circuits, battery charging circuits, and telecommunication systems.

Working Principle: The SML4749-E3/61 Zener diode operates in a reverse-breakdown mode to regulate the output voltage. When the voltage across the diode exceeds the Zener voltage, the device will enter into a conduction state, allowing a steady current to flow. The current is then limited by a specific amount, when a certain voltage is applied across the diode. The voltage across the diode will remain at a constant level, regardless of the increase of external of current. This property is also known as the Zener effect, and it is the basis of the SML4749-E3/61 Zener diode’s operation.

Structures: The SML4749-E3/61 Zener diode is constructed with a PN junction in a single package and is available in both a conventional axial leaded lead (LED) and a surface mount package. The device is constructed of two semiconductor diode chips, which have been mounted back-to-back and connected in series by a small wire bonding. The anode and cathode are then connected to a single shared voltage lead via soldered contact points.

Performance: The SML4749-E3/61 Zener diode has a low forward voltage drop, meaning that it can achieve high levels of efficiency. It also has a low Zener impedance and is capable of handling large currents up to a certain power rating. The device is designed to be reliable, with minimal leakage current and a long-term stability of the Zener current. In addition, the device has been designed with no reverse recovery charge, meaning that it can operate at higher frequencies without any interference.

Conclusion: The SML4749-E3/61 Zener diode is a versatile and reliable electronic component, which can be used in a wide variety of applications. Its simple construction, high efficiency and low cost make it an attractive option for many applications. This single Zener diode is a great choice for a wide range of applications.
