TVS - Varistors, MOVs represent vital components of many electronic systems. Their main purpose is to protect circuits from electrical transients, which can cause harmful voltage peaks that exceed the nominal operating range of the circuit and damage the device. ERZ-U22JP162F is one type of such component and has a wide range of applications. This paper will discuss the application field of the ERZ-U22JP162F and its working principle.

The ERZ-U22JP162F is basically a uni-directional voltage-dependent resistance device designed to protect sensitive electronic circuits from transients. It is designed to work in a wide range of voltages up to 220V peak and can reduce the voltage and current instantaneous spikes by clamping them to lower levels, thus protecting the device. This is due to the non-linear resistance characteristic of the device, which changes with the change in voltage across it.

The ERZ-U22JP162F is mainly used in many video applications such as LCD and plasma display circuits, VGA Cards, HDMI cables and HDTVs. The device is also suitable for other communication systems such as DSL modems, ISDN lines, WiFi / Bluetooth radios, and T-1 / E-1 lines. It is also widely used in automotive electronic components such as airbag systems, fuel injection systems, and engine control units.

In addition to its applications, another important aspect of the ERZ-U22JP162F is its working principle. As mentioned earlier, the device works based on its non-linear resistance characteristic, which changes depending on the voltage across it. When a transient voltage is applied, the internal impedance of the device decreases, thus allowing the transient voltage to be clamped at a safe level and preventing the destruction of the circuit.

The working principle of the device is also known as the “avalanche effect”, which is a voltage-induced avalanche breakdown process. When the applied voltage crosses the breakdown voltage of the device, the current will suddenly increase to levels much higher than the nominal current. This increase in current will cause the device impedance to drop, allowing the transient voltage to be discharged safely.

The ERZ-U22JP162F is a unique electronic component that has the ability to protect sensitive electronic circuits from transient voltage and current spikes. It is widely used in many video applications, communication systems, and automotive electronic components. The device works based on its non-linear resistance characteristic, which allows it to clamp the voltage peaks to a safe level and protect the circuit from damage.
