V10H11P

V10H11P is a voltage dependent surge-absorbing device, and it belongs to the most commonly used overvoltage absorption components, TVS (transient voltage suppressor), MOV (metal oxide varistor), and can widely be used for EMI (electromagnetic interference) protection and overvoltage prevention. This article is going to explain the application field and working principle of V10H11P.

Application Field

V10H11P is most often used as a component in circuit which can prevent transient voltage surge. These transients can be caused by the occurrence of lightning attacks and can cause high surges in the circuits due to the wide range of electrical parameters that can exist in EMI noise. As such, V10H11P is useful to suppress transients by either preventing, detecting, or absorbing them.

V10H11P is also often used in the protection of electronic equipment and power systems from overvoltage. It is usually fitted in the circuit to protect it from malfunctioning due to overvoltage from external sources, such as switching power supply or lightning or motor drive applications.

V10H11P is also used in situations where an electronic system may require a monitored voltage supply. For example, it can be used in solar inverter, which can help protect photovoltaic panels from breakdown due to abrupt voltage changes.

Working Principle

V10H11P is essentially a semiconductor device, which means it allows a limited amount of current to flow through it under normal conditions and when the voltage reaches a certain predetermined value, the device switches to a state where it acts like an open switch to dissipate extra voltage. This is known as voltage-dependent protection or overvoltage prevention.

In operation, V10H11P acts like a vacuum tube. On the inside of the device is a combination of a substrate and anode layer. When a voltage is applied across the anode layer, the electron current begins to flow in the circuit. As the voltage continues to rise, the electrons immediately increase, this causes the current in the substrate to be diverted from the anode layer to the substrate. As this happens electrons are being absorbed and released. When the current in the substrate reaches a certain level, the device snaps off, diverting the voltage in the circuit and absorbing it.

V10H11P is also able to absorb surge current by redirecting the electricity away from the circuit. This is because when a voltage is applied to it, the electrons in the device absorb the electricity and are then dissipated. By doing this, it is able to reduce the amount of voltage that is carried over into the circuit, therefore reducing the risk of damage to delicate components.

Conclusion

V10H11P is one of the most commonly used overvoltage absorption components, and it is widely used for EMI protection and overvoltage prevention. It has a wide range of application fields, such as lightning protection of electrical equipment, overvoltage protection of switching power supply and motor drive applications. Its working principle is based on the voltage-dependent protection principle in which it acts similarly to a vacuum tube. It absorbs the extra voltage by redirecting the electricity away from the circuit or by dissipating the electrons inside the device.
