The 1N5347BG is a single zener diode suitable for a wide range of applications. This diode acts as a steering diode, allowing current to flow in one direction while blocking it in the other. It also serves as a voltage limitation device, regulating voltage across a load.

The 1N5347BG uses a junction breakdown as its working principle. This occurs when the voltage across the diode exceeds the breakdown voltage, which is typically 8 volts for this diode. This causes a sudden decrease in the diode’s internal resistance and a rapid increase in current through it.

The 1N5347BG is commonly used in automotive applications, such as eliminating spikes from ignition systems, suppressing noise from alternators, and providing an uninterrupted power supply for electronics systems. It is also used in consumer electronics, such as in TV sets, computer monitors and DVD systems. In addition it is often used in telecommunications, to protect devices from excessive voltage transients or to regulate a wide range of operating voltages.

Practical applications of the 1N5347BG require it to be correctly connected in series with the load. This enables the breakdown effect to be used to limit the voltage and current passing through the load, while still allowing the load to operate within a desired range. The resistance of the load should be greater than the resistance of the diode, which is typically 0.6 ohms.

The 1N5347BG is a versatile diode that is simple to use. It is ideal for designers looking for a reliable solution to provide power and voltage protection, and for those who need to regulate low to medium power loads. Its wide operating temperature range (-55°C to 150°C) and peak reverse power rating of 500mW make it suitable for use in a wide variety of applications.
