MMSZ5246C-E3-08

The MMSZ5246C-E3-08 is a single discrete, silicon, planar Zener diode. It is used in various applications such as voltage clamping, reference source and voltage stabilizers. The MMSZ5246C-E3-08 is designed to have a reverse breakdown voltage of 5.1 V with +/-5 % tolerance

The simplest form of a Zener diode is that of a diode biased in reverse. Normally, a diode would break down when reverse biased to a voltage higher than a certain level, depending on the diode’s characteristics. The Zener diode is special in that it is designed to allow current to flow in reverse only up to a certain voltage, and then abruptly breakdown, allowing current to flow in both directions.

The main characteristic of the MMSZ5246C-E3-08 is its 5.1 V rating as mentioned before. This is the voltage that the diode will breakdown allowing current to flow through it. The current that will pass through the diode is determined more by the Zener impedance, Rz, than by the breakdown voltage.

The MMSZ5246C-E3-08 can be used in various applications. One such application is voltage clamping. Voltage clamping is a method of limiting the voltage across a device to prevent it from exceeding a certain level and thus avoiding damage to the device due to overvoltage. By placing a Zener diode in parallel with an electronic component and providing a certain bias voltage, the Zener diode will keep the voltage across the component below a certain level as it starts to exceed that, the Zener diode will conduct, thus limiting the voltage across the component.

The MMSZ5246C-E3-08 can also be used as a voltage stabilizer. This application takes advantage of the Zener diode’s abrupt breakdown feature. By using a Zener diode in series with a voltage source, the Zener diode ensures that the output voltage remains constant as the input voltage may change up or down. As the input voltage starts to increase or decrease, when it reaches the Zener voltage, the Zener diode starts conducting maintaining a constant voltage across the load.

The MMSZ5246C-E3-08 is also often used as a reference source. Again, its Zener diode characteristics are utilized. A Zener diode reference source places the Zener diode in series with a voltage source and allows a certain current to flow through it. This current will be enough to put the Zener diode in breakdown mode. The voltage across the diode in this scenario will remain constant as the current can flow freely, thus providing a constant voltage reference for other components.

In summary, the MMSZ5246C-E3-08 is a single discrete, silicon, planar Zener diode that has a reverse breakdown voltage of 5.1 V with +/-5 % tolerance. It is ideal for applications such as voltage clamping, reference source, and voltage stabilizers. The MMSZ5246C-E3-08 takes advantage of its Zener diode characteristics to provide a constant voltage in all of these applications.
