Diodes - Zener - Single: SML4748AHE3/5A application field and working principle

SML4748AHE3/5A is a type of Zener diode which operates with low power and is essentially a voltage regulating device. It can be used to stabilize electric circuits and protect against excess voltage. It is a learning resource used in a variety of industrial, educational, and commercial contexts.

Application Field:

SML4748AHE3/5A can be used in various parameters such as voltage regulation, clamping, and protection. It’s easy to integrate circuit design and can be used in DC-DC converters, battery protection appications, solid state relays, overvoltage protection and LED driver applications. Additionally, it can be used in the telecommunications industry, audio industry and security systems.

Working Principle:

When the anode is more positive than the cathode, the SML4748AHE3/5A Equivalent Diode will begin to conduct. At some critical threshold value of the potential difference, the electronics will begin to ‘break down’ and a large current begins to flow. To prevent this situation, SML4748AHE3/5A limits the voltage. This protection is achieved through a controlled reverse breakdown.

The exact breakdown voltage of a diode depends on its construction. SML4748AHE3/5A uses an heavily doped PN junction allowing it to achieve a voltage breakdown. The amount of dopants that have been used allows SML4748AHE3/5A to maintain a fixed voltage under a large range of reverse current. It can therefore be used for stabilizing voltages and protects the circuit components from excess voltage.

Conclusion

The SML4748AHE3/5A is a type of Zener diode which operates with low power and can be integrated into a wide array of industrial, commercial and educational applications. It is used for voltage regulation, clamping, protection and preventing excess voltage. It uses an heavily doped PN junction which allows for a fixed voltage under a wide range of current and serves as a learning resource in the telecommunications industry, audio industry and security systems.
