The GLL4747-E3/97 is a single Zener diode which is used for various purposes. These diodes are available in both through-hole and surface-mount packages, and come in a variety of breakdown voltages. They can also be used either as a regular diode or as a Zener diode.

A Zener diode is a type of diode which has a negative temperature coefficient. This means that it has a reverse breakdown voltage which is lowered as the temperature rises. This allows the Zener diode to be used in a variety of applications where the voltage needs to be precisely controlled. The GLL4747-E3/97 is ideal for these applications where extreme accuracy is required.

The GLL4747-E3/97 is typically used as a voltage regulator in power supplies, or as a voltage reference in circuits such as motor control. It is also used in various automotive applications to regulate the voltage from large alternators or batteries. In addition, it can be used in low-noise analog circuits, or for transistor biasing in amplifiers. The GLL4747-E3/97 is available in a variety of breakdown voltage ratings, from 3.3V to 85V.

To determine the breakdown voltage of a Zener diode, a common method is to use the Zener voltage equation. This equation involves the peak inverse voltage (PIV), the reverse saturation current (IS), and the Zener breakdown voltage (VZ). The equation is: VZ = PIV - IS. The PIV is the maximum voltage that can be applied to the diode in the reverse direction without damaging it, while the IS is the current that flows through the diode when the PIV is applied.

When the Zener diode is used as a voltage regulator, it is necessary to limit the current which passes through it. This is done by using a current limiting resistor in series with the diode. The current limiting resistor should be sized so that the Zener diode will not be subjected to more than its rated power.

The GLL4747-E3/97 also has a low forward voltage drop, which makes it ideal for use in switching circuits. When used in a switch mode power supply, the GLL4747-E3/97 will help keep the switching frequency high and the power supply efficient.

In summary, the GLL4747-E3/97 is a single Zener diode with a variety of breakdown voltage ratings. It is used for precise control of voltage in applications such as power supplies, motor control, and automotive electronics. It also has a low forward voltage drop and can be used for current limiting in switching circuits. With its high accuracy and reliability, the GLL4747-E3/97 is a great choice for any application.
