B72650M0271K093

The B72650M0271K093 is part of a family of Voltage Dependent Resistor (VDR) components, which form a current surge protection device for protection against transients or power surges. Protection is provided through a voltage-sensitive dielectric which breaks down and conducts any excessive electrical current when the voltage rises to a certain level.

Application Field

The B72650M0271K093 is designed to be used as part of an over-voltage protection circuit that will protect circuits against electrical transients, power surges, and other over-voltage events. The device has a self-resetting, non-linear behavior that allows overvoltages to quickly be diverted away from sensitive components. It is designed for use mainly in automotive applications such as control systems and power electronics. It can also be used in AC power line applications, DC power supply systems, telecommunications systems, and other low voltage applications.

Working Principle

The B72650M0271K093 is a Voltage Dependent Resistor (VDR) or Varistor device, which uses a Non Linear resistive element. When subjected to an increase in voltage, the resistance of the device will decrease and it will act as a conductor, thereby diverting any excess current away from the sensitive components being protected. This protects the protected device from damage due to overvoltaging. The device also has a self-resetting feature which allows it to resume its original state after an over voltage event. This makes it an ideal choice for protection against transient power surges.

The device can be operated at temperatures between -55 to 125°C and has an operating voltage range of 6.8V to 400V. The device has a peak current rating of 7 A and a clamping voltage of 450V. It also has a low leakage current of 0.2 μA.

The B72650M0271K093 is designed to provide reliable over voltage protection and can be used in a wide variety of applications where over-voltage protection is required.
