B72527G3200K000

The B72527G3200K000 is a varistor, which is also referred to as a voltage-dependent resistor (VDR) or transient voltage suppression device (TVS). Varistors are electronic components designed to protect sensitive electronic circuits from voltage transients or surges. They feature non-linear characteristics which means that they offer high resistance to small signals but rapidly decrease their resistance at higher voltages. The B72527G3200K000 is a particular type of varistor, which is specifically designed to provide general-purpose overvoltage protection for circuit boards.

The B72527G3200K000\'s application field includes various semiconductor components such as computers, modems, monitors, and other sensitive electronic equipment. It can be used in power system protection, equipment protection, and surge suppression at operating voltages up to 400V AC/24V DC. This varistor can provide overvoltage protection up to 2000V peak pulse current for up to 3000 pulses.

The working principle of the B72527G3200K000 is based on the principle of electrochemical metallization. In electrochemical metallization, a thin layer of metallic film is formed on the internal surface of dielectrics and semiconductor materials using chemical reaction. The B72527G3200K000 is composed of a polymer layer sandwiched between two parallel layers of zinc oxide. When the voltage is greater than the clamping voltage of the device, the zinc oxide layer starts to breakdown. This process creates a conductive path resulting in a rapid decrease in the resistance. As a result, the device charges up, providing protection against electrical transients and surges.

The B72527G3200K000 is a reliable device and it is suitable for a variety of applications. It can be used in various industries such as aerospace, automotive, telecom, computing, and industrial. It is a low-cost solution for overvoltage protection applications and offers reliable protection against spikes, surges, and transients.
