V60MLA0805H

TVS (transient voltage suppressor) diodes, varistors (voltage-variable resistors), and MOVs (metallic oxide varistors) are essential components for protecting circuits from destructive transient voltages. The V60MLA0805H is an innovative multilayer Metal Oxide Varistor (MOV) suitable for use in many different types of high-voltage circuit protection applications. The V60MLA0805H has a high peak pulse current (IPP) rating and excellent surge current handling capability, making it an ideal choice for high reliability applications.

The Metal Oxide Varistor (MOV) is a solid-state device with an internal structure which is composed of zinc oxide and other metal oxide particles embedded in a polymer matrix. The MOV operates by conducting current only when the voltage reaches a certain threshold, known as the breakdown voltage. When the voltage across the MOV becomes greater than the breakdown voltage, the MOV starts to conduct current. The amount of current that flows is proportional to the amount of voltage present. The point at which the current limiter begins to conduct is called the clamping voltage, or the cut-off point. This voltage can also be seen as the maximum peak value that can be stopped or clamped.

When the peak voltage of the surge is below the clamping voltage, the MOV will not conduct any current and the circuit remains unaffected. Above the threshold voltage, the MOV begins to conduct current and the circuit is protected from the surge voltage. This process is known as the clamping action of the metal oxide varistor and is dependent on the characteristics of the material and its geometry. As the surge voltage increases, the MOV dissipates more and more energy, thus limiting the rise in peak voltage to a level that is safe for the circuit components.

The V60MLA0805H is designed to meet the current needs of surge protection applications, such as telecom, industrial, automotive, and consumer electronics. It has a high current surge capability of up to 30A, while still providing excellent electrical characteristics. The 20V breakdown voltage, at an operating temperature of 85°C, ensures that the device is suitable for use in a wide range of applications. The V60MLA0805H has an I2T rating of 110A2s2/647.5 and a thermal resistance of 0.77°C/W.

The V60MLA0805H is also versatile in terms of mounting options. It is available in SMD (surface mount device) and through-hole packages. The SMD package makes use of a conductive adhesive layer that provides extra protection against cracking, ensuring long-term reliability. The device also utilizes advanced design techniques to provide a low inductance, allowing for faster response times and improved electrical performance. Additionally, the V60MLA0805H is halogen-free and RoHS compliant.

In conclusion, the V60MLA0805H offers reliable protection against high voltage surges and transients. It is an ideal choice for high-reliability applications due to its high IPP rating, excellent surge current handling capacity and advanced design features. The V60MLA0805H is available in both SMD and through-hole packages and it complies with all relevant standards, making it suitable for many different types of applications.
