TVS (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are two important components in power supply systems that protect sensitive components from damaging peak transients. The VM474MK801R040P050 is a high voltage 40V rated metal oxide varistor that can absorb high transient energy up to a maximum clamping voltage of 90V. Designed with a hermetically sealed space, the VM474MK801R040P050 is rated for a wide temperature range of -40°C to +125°C and is well established in many industrial applications as a surge protect device.

The VM474MK801R040P050 application field mainly includes but is not limited to:

• Printed Circuit Boards and Assemblies
• Surge Protectors and Transient Voltage Suppressors
• Data and Telecommunications
• Industrial and Automotive Applications

The working principle of the VM474MK801R040P050 is based on the ability of the zinc oxide material it is composed of to expand during high voltage and absorb energy. As a non-linear device, the VM474MK801R040P050 is used to reduce the peak voltage of transients in an applied voltage by clamping it to a predetermined level. This prevents the overvoltage of sensitive components as it will limit the maximum voltage to a known value. The VM474MK801R040P050 uses a hermetically sealed chamber to enclose the sensitive zinc oxide material which helps maintain its non-linear characteristics and withstands a wide temperature range.

The VM474MK801R040P050 can withstand high surge transients up to a maximum of 90V, and absorbs large amounts of current allowing it to limit the current flowing into a conductor to reduce hazards. The low resistance snap-acting characteristics of the zinc oxide material also helps to reduce voltage transients quickly and safely. Due to its wide temperature range of -40°C~+125°C and superior surge absorbing ability, the VM474MK801R040P050 is ideal for surge protection of critical components in a wide range of industrial and automotive applications.

In summary, the VM474MK801R040P050 is a hermetically sealed 40V metal oxide varistor with a low-resistance snap-acting characteristics and a maximum transient voltage rating of 90V. This device is widely used as a surge protection device in Printed Circuit Boards, Automotive Applications, and Data and Telecommunications. The zinc oxide material’s expansive characteristics help it absorb transients quickly and safely while also ensuring its low-resistance snap-acting properties are maintained throughout a wide temperature range.
