Diodes, in their most basic form, are electronic components used for switching and rectifying current, enabling current to flow in one direction only. The most common type of diode is a Zener diode, and the 1N5347CE3/TR12 is a single Zener diode. It can perform a variety of tasks, including voltage regulation and stabilisation, as well as rectification, signal mixing and power switching.

The 1N5347CE3/TR12 is a 3.3V Zener diode, which means it maintains a precise voltage level of 3.3 V across its terminals, even when the external voltage fluctuates. This makes it perfect for applications such as protecting sensitive electronic devices from spikes and dips in external voltage, providing precise voltage regulation and stabilisation for electronic circuits, and for electrical signal mixing. It can also be used as a reverse blocking element, blocking current from flowing from the diode’s anode to its cathode, while allowing current to flow in the opposite direction.

The 1N5347CE3/TR12 is encapsulated in a small, TO-92 package, making it convenient to use and suitable for a wide range of applications, including automotive, industrial, telecommunications, and audio/video equipment. It has a maximum peak repetitive reverse voltage of 5V and a maximum peak forward current of 800mA, as well as a continuous reverse current of 50mA. It also has a maximum power dissipation of 300 mW.

The 1N5347CE3/TR12 works according to the Zener effect, which occurs when an electric voltage is applied across a diode in reverse-bias. When the reverse-bias voltage reaches a certain value known as the “Zener breakdown voltage”,avalanche breakdown occurs, causing the voltage across the diode to increase, which in turn increases the current flowing through the diode. The 1N5347CE3/TR12 is designed to maintain a constant voltage of 3.3 V across its terminals, regardless of fluctuations in the external voltage, ensuring precise voltage regulation and stabilisation.

The 1N5347CE3/TR12 is an ideal choice for many applications, such as protecting sensitive electronic devices, providing precise voltage regulation and stabilisation, as well as rectification, signal mixing and power switching. Its small, TO-92 package makes it convenient to use, while its Zener characteristics make it perfect for protecting against voltage fluctuations. Its low power dissipation and current blocking capabilities make it well-suited to high-frequency switching applications, making it one of the most versatile and widely used diodes available today.
