Diodes - Zener - Single

SML4749AHE3/5A is a type of single zener diode. It is widely used in various practical applications and has a variety of features. It is highly reliable and can withstand harsh environmental conditions.

The SML4749AHE3/5A has a variety of different application fields. Its primary uses are in power supply regulation, voltage regulation, and surge protection. It is commonly used in power supplies, inverters, converters, motor control circuits, wireless systems, and optical communications. This diode can also be used in signal regeneration, line termination, and ripple suppression.

The key features of the SML4749AHE3/5A include low voltage requirements, relatively low leakage currents, an average forward voltage drop of 1 V, and a breakdown voltage of 5.6 V. It also features a high current capacity, with a maximum forward current rating of 0.2 A and a reverse current rating of 5 mA.

When it comes to its working principle, the SML4749AHE3/5A is a breakdown diode. It works by allowing current to flow in a forward direction up to a certain voltage, known as the breakdown voltage. At this voltage, the electric field in the diode reaches a point where the electric force causes electrons to tunnel across the junction and consequently, the diode breaks down. This breakdown creates a large electric field in the diode and a large current can flow through it.

The breakdown voltage of the SML4749AHE3/5A is 5.6 V, and once the voltage across the diode reaches 5.6 V, current begins to travel through the diode in the reverse direction, instead of the forward direction. This helps to ensure that the voltage in a circuit never exceeds the designed limits.

The SML4749AHE3/5A is a highly reliable and efficient device for use in a variety of different applications. Its ability to regulate voltage, protect circuits against transient spikes, and reduce the ripple voltage means that it is a valuable component in many electronic devices and systems.
