V131DA40 Application Field and Working Principle

TVS (Transient Voltage Suppressors) and MOV (Metal Oxide Varistors) are two major components used to protect electronic circuits from excessive voltages from outside sources. Among the various types of TVS and MOV, V131DA40 is one of the most popular and widely used model in current market. This article provides an overview of the application field and working principle of V131DA40.

V131DA40TVS/MOV is mainly used in systems with low or medium power. It is a type 2-byte component, composed of an aluminium oxide layer backed by a thermal insulating board and a thermally conductive non-magnetic material. V131DA40 can protect electronic circuits from a wide range of voltage transients or disturbances from outside sources, such as AC mains; the current carrying capacity is up to 120/48A (8/20 μs).

The application field of V131DA40 mainly includes various home appliances, automotive electronics, instrumentations, communication equipment and computers. This component can be broadly used in combination with multiple electronic devices for protection from voltage transients. It is designed to protect such devices from transient overvoltage surges, ESD, and lightning strikes.

The working principle of V131DA40TVS/MOV is based on the principle of capacitive discharge. When a voltage spike is detected, the capacitor within the device starts to absorb the excess voltage and discharges it through an internal current limiting resistor or a Zener diode. This process suppresses the transient voltage and protects the circuit from damage. V131DA40 also offers superior thermal and surge resistance characteristics, which makes it suitable for higher power applications.

In addition to traditional protection applications, V131DA40 can also be used in current-limiting applications. This component is capable of limiting circular current to a predetermined value, and provides low on-state impedance up to 0.63 V - 1 mA. This property makes V131DA40 perfect for overcurrent protection in broad range of electronic systems .

In conclusion, V131DA40 is a versatile TVS/MOV component with a wide range of applications. It is applicable in low/medium power systems, offers excellent protective features, superior thermal resistance, and is suitable for current limiting applications. This component is widely used in multiple mainstream consumer products and has become a must-have component for electronic systems nowadays.
