V120ZU05PX2855

The V120ZU05PX2855 is a protection device for suppressing surges. It belongs to the family of transverse voltage suppressors, which are also known as voltage-dependent resistors, metal oxide varistors (MOVs), and movable volumetric resistors. MOVs are mainly used to protect circuits from transient overvoltages caused by lightning, power equipment switching, and other fault conditions.

Varistors, or MOVs, are composed of metal oxides of zinc, iron, cobalt, or manganese, and are formed into pellets. When a voltage greater than its rated voltage is applied, the pellet of metals expands and touches the electrode, forming an interlock between them. This forms a conducting path and allows current to flow, thus diverting the excess voltage away from the protected device.

The V120ZU05PX2855 has a clamping voltage of 3V and a maximum energy rating of 1493 Joules. It is a non-polar component and can be used as a replacement for MOVs with reverse-poled DC voltage protection or AC applications. It operates in a temperature range of -40 to +85°C. It is suitable for use in telecom, power, medical, industrial, and consumer electronics applications.

Since it incorporates a low-pass EMI filter, the V120ZU05PX2855 is also effective in suppressing high-frequency electromagnetic interference (EMI). It has a wide operating frequency range from DC to several kilohertz, with a typical frequency response of 100 kHz.

In conclusion, the V120ZU05PX2855 is a high-performance, co-fired varistor used in electronics protection devices. It is suitable for use in a wide variety of applications, including those requiring high-speed transient protection, low-pass EMI filtering, DC polarity protection, and many others. It has a wide frequency range, a clamping voltage of 3V, and a maximum energy rating of 1493 Joules.
