TVS- Varistors, MOVs are widely used in electronics equipment, providing a surge protection, transient voltage protection, and even filtering against EMI and ESD. The V14MLA0805LA is one type of these devices. This article will discuss the application field and working principle of the V14MLA0805LA.

The V14MLA0805LA is a 1500W, 14VDC, 4-line surge absorber and transient-voltage suppressor (TVSS). It is available as both an 8-pin radial and an 8-pin axial form factor, and provides over-voltage protection for all lines. It is designed to protect sensitive electronic circuits from transients in the power supply due to inductive and capacitive coupling, lightning-induced surge currents, and AC power line surges. It provides excellent clamping performance, which helps guard against over-voltage conditions and EMI/RFI interference.

The application field of the V14MLA0805LA is quite broad. It can be used in power supplies, communication systems, telecom systems, AC/DC circuits, computer motherboards, and other consumer electronic equipment. In addition, it can be used as a secondary protection device for protecting sensitive electronic circuits from transients caused by lightning-induced surge currents or AC power line surges. Moreover, it can be used as a noise filter and EMI suppressor to improve system performance.

The working principle of the V14MLA0805LA is relatively straightforward. It is essentially composed of two main components: a semiconductor and a zener diode. The semiconductor component acts as a current regulator, limiting the amount of current that is allowed to pass through the device, while the zener diode acts as a voltage limiter, prevents voltage spikes that may occur in the power supply due to external sources. During normal operations, the semiconductor component is in a non-conductive state and no current is allowed to pass. However, when a surge voltage is present, the semiconductor component begins to conduct, dissipating the excess energy and limiting the amount of current that is allowed to pass. The zener diode also does its part in protecting the device by limiting the voltage that is allowed to pass to a certain level.

The V14MLA0805LA is a very useful device for protecting sensitive electronic equipment from transients caused by external sources such as lightning-induced surge currents or AC power line surges. It can also be used as a noise filter and EMI suppressor. It is available in both radial and axial form factors, which makes it easy to install and highly versatile. In conclusion, the V14MLA0805LA is an effective and reliable solution for protection and noise filtering needs.
