TVS - Varistors, MOVs

The V14MLA1206NHAUTO is an automotive-grade transient voltage supressor (TVS) diode. This device is designed to protect sensitive circuit components against electrical transients due to electrostatic discharge (ESD), inductive switching, and capacitive coupling. It works by clamping overvoltage when it reaches the peak of a transient.

The V14MLA1206NHAUTO is typically used to protect automotive electronic control units (ECUs) from high reverse working voltage, EMI (electromagnetic interference) and ESD. It can be used in ECU I/O ports, ignition control systems, anti-skid brake systems, and other electronic control systems. It is designed to operate in temperatures ranging from -40°C to +125°C.

Features and Benefits

The V14MLA1206NHAUTO features a low clamping voltage, a high peak-pulse current rating, and a low capacitance. Its peak pulse power is rated up to 270W (8/20µs waveform), and its forward working voltage is rated up to 6V. It is AEC-Q101 qualified, making it suitable for use in automotive applications. The device is also RoHS compliant and UL recognized.

Working Principle

TVS diodes work by clamping overvoltage when it reaches the peak of a transient. They are designed to withstand very high levels of surge current and protect sensitive circuit components from being damaged during electrical transients. The V14MLA1206NHAUTO works in a similar fashion.

When a surge voltage is applied to it, the device absorbs the energy, clamping the voltage at a safe level. This protects the sensitive components of the ECU from being damaged by the transient voltage. The device can handle high peak currents and dissipates any energy that is absorbed during the surge.

Conclusion

The V14MLA1206NHAUTO is a transient voltage supressor specifically designed for automotive applications. It is capable of protecting sensitive circuit components from high reverse working voltage, EMI, and ESD. Its features include a low clamping voltage, a high peak-pulse current rating, and a low capacitance. It is AEC-Q101 qualified and RoHS compliant.

The device works by clamping overvoltage when it reaches the peak of a transient. This helps to protect sensitive components from being damaged during electrical transients. With its high peak-pulse current rating and low capacitance, the V14MLA1206NHAUTO is an ideal choice for use in automotive electronic control units.
