Introduction

B72650M0140K093 is a miniature metal oxide varistor (MOV) widely used in the industry. It is a nonlinear resistor that changes its electrical characteristics depending on the applied voltage. MOVs provide surge protection to a wide range of electronic equipment ranging from communications equipment to semiconductor devices. MOVs provide a shunt path for current to ground when applied voltages exceed the device threshold, effectively protecting the underlying circuit from the harmful effects of overvoltage.

Application Field

The B72650M0140K093 is an effective solution for applications with a nominal operating voltage up to 140V AC. This MOV withstands multiple 8/20 uS waveform impulses up to 40kA. These values mean that this MOV can handle relatively high voltage surges before allowing the current to shunt to ground. This makes the B72650M0140K093 a strong candidate for protecting a wide range of electronic equipment.

The MOV is especially effective for protecting semiconductors, capacitors, and other sensitive electronic components where the occurrence of an overvoltage event could cause permanent damage. The MOV can safely absorb temporary surges in voltage that may be caused by power line spikes, lightning, or other environmental generated events that can potentially damage circuitry.

Working Principle

The B72650M0140K093 works on the principle of a Zener Diode. A Zener diode is a special type of diode that exhibits the same characteristics as a normal diode, except that it allows a current to flow in both directions, even at reverse bias, provided the applied voltage exceeds the “Zener Voltage”. This allows the diode to absorb surges in voltage that may otherwise cause the underlying circuit to be permanently damaged.

In the case of the B72650M0140K093, the MOV works in a similar fashion. When the applied voltage exceeds the set threshold voltage, a shunt path will be created, allowing the current to flow away from the underlying circuit instead of damaging it. This prevents any further damage to the associated components, while allowing the underlying circuit to operate normally.

Conclusion

The B72650M0140K093 is a miniature metal oxide varistor (MOV) used for a wide range of applications where the occurrence of an overvoltage event could potentially cause permanent damage. MOVs provide a shunt path for current to safely flow away from the underlying circuitry instead of causing potential damage. This makes the B72650M0140K093 an effective solution for protecting a wide range of electronic equipment, including semiconductors, capacitors, and other sensitive components.
