TVS or Transient Voltage Suppressors, MOVs, and Varistors are devices used to protect components from electrical transients. When there is an overvoltage, these devices are designed to reduce or inhibit the current surge, protecting the surrounding components from damage. This article will discuss the V18AUMLA1206NA application field and working principle.

Overview of V18AUMLA1206NA

The V18AUMLA1206NA is a discrete TVS (Transient Voltage Suppressor) device. It is designed to protect sensitive components from voltage surges or spikes. The V18AUMLA1206NA is a surface-mount device, and is part of a family of high-speed, surge-protecting, voltage-clamping devices from EPCOS. It is specifically designed for automotive applications, as it offers a low-voltage drop and high electrical stability.

The V18AUMLA1206NA also features a low impedance body to reduce the generation of inductive noise and high clamping voltage for protecting up to 1.5kV surge. It also has an ultra low leakage current and ultra low clamping voltage to enhance the reliability of automotive power circuits.

Application Field and Operation

The V18AUMLA1206NA is used in automotive power circuits to protect sensitive electronics from transient surges which often occur due to switching loads, induced or radiated noise, and lightning strikes. This device is designed to protect delicate electronic circuit components such as microcontrollers, processors, bus lines, and memory modules.

The V18AUMLA1206NA operates by clamping the surge voltage before it reaches the protected component. When the transient voltage exceeds the operating voltage threshold, the TVS turns on and starts emitting current. The device\'s low-impedance body works to reduce the level of emitted current and protect the components. The device\'s high clamping voltage also limits the voltage to a safe level.

The V18AUMLA1206NA is designed to offer a high level of EMC (electromagnetic compatibility) for applications which must adhere to the strict requirements of modern automotive safety efficiencies. It has an exceptionally low leakage current rating of 1µA at 100V, which helps to protect circuits with low power consumption and extend their functional life. The device also conforms to the latest automotive safety certifications, ensuring compatibility with the latest automotive standards.

Conclusion

The V18AUMLA1206NA is a surface mount voltage transient suppressor designed specifically for use in automotive power circuits. It offers a high level of EMC compatibility, a low-impedance body, a low leakage current rating of 1µA, and a high clamping voltage of 1.5kV. Its operation involves clamping the surge voltage before it reaches the protected component, thus offering excellent protection against transient surges. This device is designed to meet the latest automotive safety standards and extend the lifespans of sensitive electronic components in automotive circuits.
