MOV-20D151K Varistor operates by dissipating voltage spikes as heat generated across an oxide layer. It is generally a metal oxide semiconductor that is a critical component of a TVS (Transient Voltage Suppressor) circuit. The MOV-20D151K Varistor found in TVS circuits is an excellent solution for effectively clamping voltage in circuits.

The MOV-20D151K Varistor is a non-linear device that is designed to provide circuit protection from voltage spikes, electric shock, and radiated interference. In its most basic form, the device can be thought of as an insulated metal oxide with a high conductivity. The electrical properties of this oxide layer allow the device to dissipate the energy created by a voltage spike, thus providing protection to sensitive electrical components and circuits.

When there is an excessive voltage spike or over-voltage condition, the MOV-20D151K Varistor will instantly conduct the current away from the load and to the ground, protecting the device from further damage. The MOV-20D151K Varistor is also used in the reverse direction to keep electrical components from being over-stressed.

MOV-20D151K Varistor is ideal for applications in automotive, consumer electronics, telecommunications, and other industries. It can be used in power supplies, data isolation circuits, and other electronic devices to prevent damage due to voltage or current surges. It is also suitable for voltage and current spike protection in AC and DC circuits.

The MOV-20D151K Varistor also provides protection against over-current, surges, and over-voltage events. It helps shield devices from high-energy transients such as inductive kickbacks, lightning strikes, and power-line surges. Thevaristor also provides protection against very fast transients, instantaneous over-voltages, and is especially effective for EMI protection.

The working principle of MOV-20D151K Varistor is relatively simple. When a voltage surge or spike passes through the MOV, the voltage causes the oxide layer to become conductive, and the current is diverted away from the load. This provides effective protection from any voltages that exceed the breakdown voltage rating.

When the voltage subsides, the MOV-20D151K Varistor’s oxide layer returns to its nonconductive state and the current drops to zero. This helps protect the circuit or device from further excessive voltages and over-currents. The MOV also helps protect against EMI as it has a high capacitance and resistance to interference.

MOV-20D151K Varistor is a reliable and cost-effective solution for over-voltage and over-current protection. It has a wide operating temperature range and is also suitable for applications that require low leakage current and high peak surge current capability.
