B72220S0171K531 is a component from the class of TVS - Varistors, MOVs. This component is especially suitable for general-purpose protecting circuits that provide protection against overvoltage transients.
Application Field
B72220S0171K531 is a surface mount type/radial leaded transient voltage suppressor which has been designed to protect exposed components against overvoltage transients such as surges caused by lightning, electrostatic discharge, induction or contact with high voltage lines. These components are designed to protect electronic devices from voltage surges and spikes in AC and DC circuits. It can also be used in a wide range of high power transient voltage suppression applications such as power supplies, lighting, industrial control systems, and telecommunications, etc. It has a wide operating temperature range of -55 °C to 125 °C. It can withstand surge currents of up to 550 A (8/20 μs) and has a low leakage current of 3 μA maximum. It also has a high peak power rating of 79,000 W and a high breakdown voltage of 175 V, allowing it to handle up to 32 A of continuous current.
Working Principle
B72220S0171K531 utilizes an MOV or a Metal Oxide Varistor for its working principle. They are non-linear temperature dependent electronic components designed to protect circuits against transients. It works by clamping off all voltages above its threshold voltage. When it is challenged with a current greater than its threshold, it acts as a short-circuit, allowing the current to pass through it. This clamps off the voltage, reducing it to the breakdown voltage of the device. It also acts as an active surge protector, as it acts to absorb energy from a transient and safely dissipates the energy.
B72220S0171K531 is one of the best-performing transient voltage suppressors devices in the market. It offers superior protection from overvoltage transients, helping to protect circuits from spikes and surges. It has a wide operating temperature range, high peak power rating, and a low leakage current. This makes it suitable for a wide range of applications.
