ERZ-SF2MK820 application field and working principle are important technological fields of surge protector products, particularly those related to TVS (Transient Voltage Suppressors) and MOV (Metal Oxide Varistors).

In television displays, the values of various voltage and current indicators must often be stabilized in order to avoid affected components and systems from being destroyed. This is where the ERZ-SF2MK820 products come in. They are designed to absorb and dissipate excess voltage and current, thus providing protection for electronic components and systems from hazardous electrical disturbances.

The working principle of the ERZ-SF2MK820 series products is to limit the instantaneous voltage surges and power disturbances. The MOVs would change their electrical properties in response to voltage changes thus regulate the voltage until it is within a safe range. In the same way, the TVS would also work within the same application field thus securing the mentioned electronics from dangerous electrical spikes.

Both devices work in a very similar way: they both rely on the nonlinearity of a semiconductor material, such as silicon, to control the amount of current passing through the device. The use of this material ensures that the device remains transparent until the current reaches a certain level, at which point the nonlinear behavior produces an avalanche diode effect and the voltage is clamped to a safe level.

The ERZ-SF2MK820 series also work with the same principles, offering effective protection against voltage spikes, transient fluctuations, and high current. This series is designed for application areas including automotive, home appliance, industrial equipment, and communications.

The MOV (Metal Oxide Varistor) is a voltage dependent resistor. It\'s operating principle is to limit the voltage overshoot by relying on the nonlinear characteristic of the component. This device can provide over voltage protection and protect sensitive components, during surge or transients. The MOVs’ circuit design determines its voltage and current ratings.

When the MOVs reaches its breakover voltage, its resistance will drop suddenly, reducing the voltage. At the same time, the stored energy in the MOV\'s electrodes will cause it to heat up, thereby further reducing the total voltage. As the voltage decreases, the resistance of the MOVs will increase, allowing the voltage to remain at a safe level.

Lastly, the TVS diode is a semiconductor device with a low breakdown voltage that can protect against transients and over-voltage conditions. It behaves similar to a MOV, but with a faster voltage clamping time. It is widely used in a range of electronic devices, automobiles, and industrial equipment to protect against hazardous voltage conditions.

In conclusion, the ERZ-SF2MK820 series products are designed to work as both MOV and TVS and offer a comprehensive protection solution against voltage surges or transients. Its protection field is quite broad and it can be used in a variety of applications to ensure the safety and reliability of the system and its components.
