1N825E3

The 1N825E3 is a 3-volt Zener diode developed for a wide range of applications. Its 5.0mA power rating makes it suitable for low-current applications. As with all Zener diodes, the 1N825E3 works by stabilizing voltage in the circuit it is placed in. A Zener diode is designed to behave as a conductor in forward bias, that is, when the anode (positive) is connected to the more positive voltage and the cathode (negative) is connected to the more negative voltage. However, when the same diode is placed in reverse bias, meaning the cathode is connected to the more positive voltage and the anode is connected to the more negative voltage, it begins to behave like a resistor. This is called the Zener effect.

The 1N825E3 is designed to have a maximum reverse breakdown voltage of 3 volts, meaning that the voltage across the diode will not rise beyond this level. This voltage is known as the Zener voltage, and it is maintained until the current passing through it reaches the Zener current, which is the maximum current for the diode to remain in its Zener region. Because the voltage across the diode is stabilized, it is used in circuits to maintain a constant voltage, such as in voltage regulators or surge protectors. In addition, the 1N825E3 is designed to have a large maximum power dissipation, meaning that it can handle more power than other types of diodes.

The applications of the 1N825E3 are varied and include, but are not limited to, power supply circuits, voltage regulators, surge protectors, reverse voltage protection, automotive distribution panels, and many others. When used in these circuits, the 1N825E3 is designed to clamp any voltage above the 3-volt level and keep it there, thus providing stable operation and protection from voltage fluctuations. For example, when placed in a power supply circuit, the 1N825E3 will clamp any voltage above 3-volts from exceeding that level, protecting other components from overvoltage. Similarly, when placed in a voltage regulator circuit, the 1N825E3 will maintain a constant voltage across the circuit, providing stable operation.

In conclusion, the 1N825E3 is a 3-volt Zener diode designed for a wide range of applications. Its 5.0mA power rating makes it suitable for low-current applications, and its large maximum power dissipation allows it to handle more power than other types of diodes. Its applications include power supply circuits, voltage regulators, surge protectors, reverse voltage protection, automotive distribution panels, and many others. When placed in these circuits, the 1N825E3 is designed to maintain a constant voltage, thus providing stable operation and protection from voltage fluctuations.
