B72580E1140S262

TVS – Varistors, MOVs – are one of the most important components in electronic circuits, providing protection against over-voltage and over-current situations. The specific purpose of a Varistor or MOV is to divert excess current away from sensitive components, so that they don\'t risk destruction. The B72580E1140S262 is a varistor specifically designed to provide protection for circuits dealing with AC and DC voltages from 6.8V to 1140V.

The B72580E1140S262 is a square, non-polar Silicon Varistor. The varistor reacts to transient voltages that exceed its rated clamping voltage (Vcl). Under these circumstances, the varistor’s designed-in resistivity decreases suddenly and the device starts conduction of the temporary overload current. After the transient pulse is gone, the varistor returns to its high-resistance state.

Applications for the B72580E1140S262 include motor drives, amplifiers, inverters, sensors and high-power rectifiers. Additionally, the varistor can provide surge protection for appliances with global AC/DC circuit boards, surge protection for industrial equipment, and lightning/surge protection for optoelectronics.

The B72580E1140S262 offers an insulation resistance of over 10⁸ Ω in a wide operating temperature range from -40°C to 85°C. The device is available in a 25mm x 25mm square package, allowing it to easily integrate into a standard circuit board design. The varistor also features a steady 0.1mA leakage current, making it an ideal choice for low-noise power systems.

The B72580E1140S262 is designed to have a good response to transients, providing effective surge protection for sensitive systems. The varistor offers a low voltage clamping and high reliability, ensuring that it remains operational under high surge current conditions. Its non-polar construction also eliminates the need for polarity protection, reducing component count and lowering overall system cost.

In summary, the B72580E1140S262 provides a reliable, effective surge protection solution for AC/DC circuits. The varistor features an insulation resistance of 10⁸ Ω and a 0.1mA leakage current, allowing it to integrate easily into sensitive circuits. Additionally, the device’s non-polar construction eliminates the need for external polarity protection, resulting in a circuit design that is simple, affordable, and effective.
