Varistors, or voltage-dependent resistors (VDRs), are essentially resistors with a variable resistance that depends on the applied voltage. This mechanism makes them suitable for applications such as overvoltage protection, undershoot protection, EMI noise suppression, and voltage clamping. Most varistors are semiconductor devices, hence called Varistor Semiconductor Devices (VSDs). One of the most popular VSDs is the B72520T1200K62 varistor, which is highly reliable, compact, and cost effective.

The B72520T1200K62 varistor is a zinc oxide nonlinear resistor designed to protect circuitry from transient voltage spikes, or surges. It consists of a disc-shaped mass of ceramic material with two metal electrodes, one on the top and one on the bottom. Its size is 8mm, and its characteristics are suited for a maximum peak pulse current of 8kAmps and a maximum clamp voltage of 1150V AC.

The B72520T1200K62 varistor has a very distinctive application field and working principle. Its application includes surge protection for communication lines, sensors, measuring circuitry, and electronic control units; EMI/RFI suppression; overvoltage and undervoltage protection; and voltage clamps and snubbers for TV receivers, IT equipment, and medical electronics. Its working principle mainly revolves around the principle of non-linear resistance. When a transient voltage spike is applied across the varistor, the current flows through the varistor and thus, enables the clamping effect. The magnitude of the current depends on the applied voltage and the varistor’s characteristics, including its maximum peak pulse current and clamp voltage.

As the B72520T1200K62 varistor can clamp transient voltage spikes, surges, and EMI/RFI noise while preventing damage to the connected equipment, it provides reliable protection. Moreover, it is known for its low power loss, low thermal runaway, and high pulse energy capability, which makes it suitable for a wide range of applications. Additionally, its low cost and small size makes it suitable for a vast range of industrial and consumer electronics.

In conclusion, the B72520T1200K62 varistor is a reliable and cost-effective device suitable for applications that require protection against transient voltages, EMI/RFI noise, and overvoltages. Because of its compact size and low cost, it has found countless applications across many industries. It is characterized by its non-linear resistance, low power loss, low thermal runaway, and high pulse energy capabilities, making it a popular choice for EMI/RFI suppression, overvoltage and undervoltage protection, and surge/transient protection.
