TVS - Varistors, MOVs

ERZ-U26JP162F is a surge absorber that belongs to the class of varistors or metal-oxide varistors (MOVs). MOVs are commonly used as protection devices for sensitive circuits against sudden large voltage surges, high transient voltages and electrical noise occurring on power cables.

ERZ-U26JP162F is specifically designed for high interference reception applications such as base stations, modems, switches and DSL routers. The product features a high peak power capacity of 26A/6V for lightning protection and a low current of 0.2mA and 0.2KV for noise protection.

The ERZ-U26JP162F is a single-channel transil, working on the principle of a general two-terminal (or three-terminal) transient voltage suppressor. Its working principle is based on the principle of a diode\'s avalanche breakdown phenomenon. The key feature of a single channel MOV is that it provides a short-circuit path for the transient voltage, allowing the transient current to pass, thus providing a sense of protection from the transient voltage.

The ERZ-U26JP162F deals with high break-down voltage, low capacitance, low thermal impedance and low clamping voltage. Additionally, the device operates in the temperature range from -40°C up to +85°C, displaying a maximum capacitance value of 1050pF at 1MHz. It is based on a metallized polyester, and is optimized for application in telecommunication lines.

In terms of installation, the ERZ-U26JP162F can be mounted on printed circuit boards through wave soldering. The two-sided terminals (pads) are made of either tin- or nickel-plated through-hole pins. The device itself is encapsulated in epoxy resin which contributes to the protection against external corrosion and oxidation.

When used in electrical circuits, the electric power surge from any external source is expected to be channeled through this small device. It will absorb the said voltage surge and reduce its effect on the rest of the circuit. The device’s performance is best when it is employed in tandem with an inductor that may control the amount of current flow.

In summary, ERZ-U26JP162F is an effective protection device for equipment sensitive to high voltage surges. By working in the principle of avalanche breakdown phenomenon, it can suppress the current level to an acceptable value, and protect sensitive units from the effect of power fluctuation.
