A SML4749HE3/61 belongs to the category of Diodes - Zener - Single. It is a type of diode that compositions of two different layers of silicon and makes use of the reverse biased junction breakdown process to limit the voltage or electric current passing through it. Since it is one of the most common types of diodes, it is often applied for different electric circuits.

Application field

The SML4749HE3/61 can be used in an array of applications, including voltage regulators, power supplies, protection circuits, as well as signal and waveform shaping. In terms of electricity capacity, it can handle up to 3A, making it suitable for both high-power and medium-power applications. It also has a wide operating temperature of -55 to 125 degrees Celsius. What’s more, it provides a low leakage current of 1.5 μA max for high precision measurement, assuring accuracy and quality control.

Working principle

The SML4749HE3/61 works by limiting the current passing through it, thus safeguarding the rest of the circuit from damages caused by high voltage or current. Its ability to provide a stable voltage from electrical connections or components makes it perfect for power supplies. The diode is regulating the process of conduction, where electrons flow from the anode to the cathode. It also allows electric current pass through in the reverse direction in order to maintain the threshold of the circuit’s voltage-current ratio.

In essence, the SML4749HE3/61 is a type of diode in the form of two layers of silicon. It uses the process of reverse biased junction breakdown to regulate current and voltage, making it a suitable choice for different applications such as voltage regulators, signal and waveform shaping, as well as protection circuits. Thanks to its wide operating temperature and low leakage current, it is a reliable, long-lasting and quality-controlled device for many electric circuits.
