Diodes - Zener - Single

The 1N4749AHR0G is a single-diode Zener-regulated voltage regulator. This device is a category of diode that includes all forms of semiconductor junctions and devices used to allow current flow in only one direction, and to regulate the voltage in a circuit.Zener diodes are designed to use the Zener effect, a physical phenomenon in which an electric current flows more easily in a reverse-biased diode than in a forward-biased diode. The 1N4749AHR0G is a particularly low-voltage variety of Zener diode which features a breakdown voltage of 4.7V, meaning it will not go over that voltage at operating temperature.The application fields of 1N4749AHR0G are vast. The most important feature of this Zener diode is its inherently low breakdown voltage of 4.7V. This makes the 1N4749AHR0G particularly well-suited for applications such as voltage regulation or DC-DC switching circuits where predictability and low voltage are needed.Additionally, it can also be used in safety applications, such as automotive seatbelt or airbag-sensing circuits. It’s versatility makes it a reliable choice for a wide variety of projects.It is a popular device for hobbyist electronics enthusiasts because it is easy to use and affordable. Voltage regulation is one of the key tasks of a Zener diode, and the 1N4749AHR0G performs this function with few problems.The working principle of 1N4749AHR0G is simple. It is essentially a reverse biased diode, meaning electricity will only flow through it in one direction. This causes a voltage drop, depending on the current and voltage indicated in its specifications.When connected to a source, the Zener diode will regulate the voltage by dropping off any excess above its specified breakdown voltage. This makes it possible to have a reliably consistent voltage across a circuit, usually significantly below the source voltage.The advantage of using a 1N4749AHR0G is that it can be used in a wide variety of applications, from power supplies to computer motherboard components. It is also incredibly low-cost and simple to use, making it widely applicable.The 1N4749AHR0G has a critical temperature coefficient of 6.4 mV per degree Celsius, a maximum reverse leakage current of 2.5 μA at 5V and a power dissipation of 500 mW, making it able to handle a variety of power loads and temperature ranges.The current that 1N4749AHR0G can block is limited as well and must be kept within the maximum ratings of the device. This means that it will take some trial and error to ensure that the current flowing through the diode stays within the limits set by the datasheet, but with the right combination of current and voltage, you can be assured that the 1N4749AHR0G will do its job of regulating a circuit’s voltage with precision.The 1N4749AHR0G is a reliable and affordable device, making it suitable for a variety of applications. Thanks to its low breakdown voltage of 4.7V, it can be used in a number of projects, from basic voltage regulation to safety applications. The 1N4749AHR0G is an essential part of any electronics enthusiast’s toolbox, making it a necessary part of any hobbyist, engineer, or technician’s work.
