TVS (Transient Voltage Suppressor) devices such as varistors, MOVs (Metal Oxide Varistors) are electrical protection components utilized in many applications. VE17P00151K, which is one of these TVSs, is a popular varistor that has found its role in a huge number of applications. This article talks about the application field and working principle of VE17P00151K.

VE17P00151K is a single row radial lead varistor that is primarily used to suppress overvoltage transientes such as lightning surges and switching surges. It has a working voltage of 170V AC (265V DC) and maximum peak current of 17A, making it a popular choice for applications such as automotive electronics, industrial equipments, home appliances and power supplies.

The outer shell of VE17P00151K is composed of a special ceramic material which is known for its excellent temperature stability and resistance to cracking. The outer shell of the varistor is also designed to dissipate heat which is generated due to overvoltage surges. It also features an internal insulation layer to ensure safe operation in highly charged environments.

Internally, the varistor contains a metal oxide material which acts as a resistor. This metal oxide material acts like a semiconductor and features a unique non-linear resistance characteristic. The resistance of the metal oxide material increases exponentially as voltage across it increases. This non-linear resistance characteristic allows VE17P00151K to suppress transient overvoltages without affecting normal circuit operations. This makes it an ideal choice for protecting sensitive electronics from electrical surges.

In normal operation, the varistor operates as a low resistance allowing normal current to flow through the circuit. However, in the event of an overvoltage surge, the resistance of the varistor increases exponentially, suppressing the surge and preventing it from reaching the vulnerable components. This self-regulating properties of VE17P00151K makes it perfect for protecting sensitive components from damage due to transient overvoltages. Apart from providing protection, it also reduces component stress and extends the life of the circuit.

VE17P00151K is well suited for use in both AC and DC applications. It can handle a life time surge energy of up to 300J making it perfect for use in applications where lightning protection is needed. It is also a good choice for protecting high power circuits and provides excellent protection against repeated transient surges.

To sum up, VE17P00151K is a single row radial lead varistor that is designed for heavy-duty surge protection applications. It is an ideal choice for protecting sensitive electronics from damage due to overvoltages. It is a reliable and cost effective solution for protecting high power circuits and offers excellent protection against repeated transient surges.
