Diodes are widely used in a variety of electronic applications. Within this broad category, Zener diodes are used for voltage regulation, telecommunications line protection and temperature sensing. One example of Zener diode is the lN5347AE3/TR8, which belongs to the category of single Zener diodes. This article will discuss the application field and working principle of the lN5347AE3/TR8.

The lN5347AE3/TR8 is a single 2.0 W, 5.1 V transient voltage suppressor diode with a maximum operating temperature of 150°C. It features a low reverse leakage current at 5.1V, a high temperature operating stability and is designed to provide reliable, low-stress overvoltage protection. This device can be used in protective circuits in telecommunication, automotive, and computer equipment.

In terms of its applications, the lN5347AE3/TR8 is used to suppress noise pulses in electronic circuits, as well as to protect against electrical surges and spikes. Its small form factor and low capacitance make it the ideal choice for a variety of automotive, communication and computer applications, including: AC power supplies, battery chargers, DC-DC converters and switches, vehicle parts and communication lines.

Regarding the working principle of the lN5347AE3/TR8, this device has a simple operation consisting of two terminals, an anode and a cathode. In normal operation, current flows from the anode to the cathode, allowing current to pass through the diode. When the voltage across the diode becomes too high, it starts to become forward biased and current begins to flow in both directions. This is referred to as “avalanche breakdown”, and is the primary function of the diode.

When a Zener diode is reverse biased it acts as an open circuit, providing no current or voltage. When the voltage across the diode reaches the breakdown voltage, it is forward biased and allows current to flow. This breakdown voltage is precisely tuned by the manufacturer, ensuring that it will not exceed the specified breakdown voltage, regardless of the direction of flow. As a result, Zener diodes are able to maintain a constant voltage across the device, providing voltage regulation and protection to the circuit.

Overall, the lN5347AE3/TR8 is an ideal choice for a variety of applications involving the protection of sensitive electronics from sudden surges of electricity. This device is specifically manufactured to withstand high temperatures and transient voltages, making it an ideal choice for a wide range of equipment and applications. The lN5347AE3/TR8 is an excellent example of a single Zener diode, and its application field and working principle are worthy of further study.
