Diodes - Zener - Single

JANTX1N4118C-1 is a single Zener diode configured in a standard two-lead packaging, often used for the purpose of limiting or stabilizing voltage. It is a very common and economical semiconductor device found in several types of applications and can be found in multiple different packages depending on the application.

Description

JANTX1N4118C-1 has a maximum voltage of 11V, with a maximum power of 500mW, and an avalanche rating of 20uA. The package comes with a standard lead pitch of 1.8mm, making it suitable for high-density in-line applications. The Zener diode also has very low forward voltage, making it suitable for Shunt regulators and other fast-switching applications.

Application Fields

The JANTX1N4118C-1 is typically used in a variety of applications, such as regulating the voltage of AC or DC input, over-voltage protection, voltage clamping, voltage reference or voltage limiting. It is commonly used for a wide range of voltage regulation purposes, including the conventional regulators, DC-DC converters, LED drivers, and lightning protection.

The common voltage range for JANTX1N4118C-1 is 9V-11V, providing a quick way to make a stable voltage regulation system. This is usually done by connecting the diode to a capacitor or another voltage reference module. It can also be used to provide over-voltage protection for voltage sensitive components. This is usually done by connecting the diode in the reverse direction in the circuit.

Working Principle

JANTX1N4118C-1 is a Zener diode, meaning it functions by allowing current to flow from its anode (positive) side to its cathode (negative) side in both directions - an effect known as Zener breakdown. In this way, JANTX1N4118C-1 operates as a voltage-regulating or voltage-stabilizing device. In this process, the voltage across the diode remains relatively constant regardless of the input voltage.

The Zener breakdown is caused when the PN-junction of the diode is reverse biased and there is an increased amount of voltage flowing through it. When this voltage reaches a certain point (known as the breakdown voltage), the diode begins to conduct, allowing current to flow through it in both directions. This causes the voltage across the diode to remain constant and ensures that the voltage of the output is also steady.

Conclusion

The JANTX1N4118C-1 Zener diode is a very inexpensive and reliable two-lead semiconductor device that is often used to provide voltage regulation or voltage stabilization in a wide range of applications. It can be easily implemented in both AC and DC circuits, making it the diode of choice for many power and voltage-sensitive applications. It is also available in various packages, depending on the application.
