This feature allows it to be used in reverse voltage protection applications, such as regulating the voltage of high-power supplies.The JANTX1N4118DUR-1 has an operating temperature range of -65 to +150°C, with a storage temperature range of -65 to +150°C. Its power dissipation is 160 mW and its maximum forward current is 500 mA. It mounts to a DPAK surface-mount package and is RoHS compliant.

Application Fields

The JANTX1N4118DUR-1 Zener diode can be used in a variety of applications, ranging from consumer electronics to military and aerospace applications. Its wide operating temperature range makes it ideal for use in outdoor applications, while its reliable and consistent performance make it an excellent choice for power supplies and test equipment.In consumer electronics, it can be used to regulate the power supply and protect against overvoltage. In automotive applications, it can be used in sensors and ECUs to protect against electrical surges. In military and aerospace applications, it is often used in power supplies for Uninterrupted Power Supplies (UPS) and in bombproof circuit boards.

Working Principle

The JANTX1N4118DUR-1 Zener diode operates on the principle of a breakdown voltage. This is achieved by connecting the anode of a PN junction transistor to the anode of the diode. When reverse-biased, the voltage across the diode increases until it reaches the breakdown voltage of the diode, at which point it “breaksdown” and current is no longer allowed to pass through the diode. When the reverse voltage exceeds the breakdown voltage, a forward current is allowed to flow through the diode, thereby “clamping” the voltage to a fixed level. This is known as voltage “clamping” and is used to protect circuits from electrical surges.In applications where the voltage needs to be regulated, the JANTX1N4118DUR-1 can also be used with a voltage-dependent resistor. This allows for precise control of the voltage, as the resistor reduces the current as the voltage increases, resulting in a decrease in the breakdown voltage.

Conclusion

The JANTX1N4118DUR-1 is an ideal choice for designers looking for reliable and consistent performance in a wide variety of applications. From consumer electronics to military and aerospace applications, its reverse breakdown voltage makes it a great choice for reverse voltage protection and voltage regulation in high-power supplies. Through the use of a voltage-dependent resistor, it can provide precision control as well as protection.
