TVS - Varistors, MOVs: V10P50P Application Field and Working Principle

Varistors, also known as Voltage Dependent Resistor (VDRs), are semiconductor components whose electrical resistance changes according to the applied voltage. This voltage-dependent behavior is utilized for a range of applications, including protection of sensitive electronics from overvoltage, voltage transient, and a range of other purposes. The V10P50P type of varistor from Vishay is a popular device used for these types of applications due to their high surge energy capacity and affordability. In this article, we will explore the application field, working principle, as well as other benefits of the V10P50P varistor.

Applications of V10P50P

One of the main applications of the V10P50P varistor is in automotive voltage protection, where the device is used to protect sensitive electronics from spikes in voltage caused by alternator charging and other in-vehicle sources.The V10P50P varistor can also be used to provide surge protection for household electronic circuits such as television, washing machines, and pianos. Additionally, the V10P50P device can also be used to protect consumer electronics from power fluctuations and over-current.

Working Principle of V10P50P

At its core, the V10P50P varistor is composed of zinc oxide particles that are arranged in a matrix. These particles are encased in a resin material and sealed by an insulating material. The main purpose of the V10P50P is to protect against transient voltages, in other words preventing sudden surges in voltage.Upon application of a voltage surge, the Zener Voltage of the V10P50P lowers its resistance to allow current to flow through the device, thereby diverting the extra energy away from the protected circuit components. This process restricts the voltage rise to a safe level, thus protecting the circuit against damage.

Benefits of V10P50P

The V10P50P offers several benefits over other varistors in the same product category. Firstly, due to its 10x20x50mm dimensions, the device is extremely compact and can be easily fitted into any space-constrained application.The V10P50P also features an excellent Surge Energy Rating of 300 Joules at an 8/20 μS waveform, making it highly effective in suppressing voltage transients. In addition to this, the device features an extremely short response time of about 5 nanoseconds, making it ideal for applications requiring quick response times.Finally, the V10P50P offers excellent leakage current which is less than 0.4mA at rated voltage, allowing it to provide effective protection against electrical and electronic component damage.

Conclusion

The V10P50P varistor from Vishay is a popular device that offers many advantages over other varistors in the same product category. It finds wide application in automotive as well as consumer electronics to provide protection against transient voltage spikes and overcurrents.The device is composed of zinc oxide particles in a matrix housed by a sealed encapsulation and features high surge energy rating, response times, and low leakage current. This makes it an ideal choice for voltage protection of sensitive electronics circuits.
