TVS (Transient Voltage Suppressor), MOVs (Metal Oxide Varistors) and other devices are commonly used to control the discharge of electrical transients in various power systems. The B72250L0271K102 is such a device that is designed to protect sensitive electrical and electronic systems from overvoltage transients for a wide range of applications.

The B72250L0271K102 device is a 6-pin leaded Disc Varistor, which is constructed with multi-layer electrodes and flame-retardant epoxy. It features a temperature coefficient of +300PPM/°C and a surge current capability of 1500A. The device has an operating voltage of up to 50VDC and a clamp voltage of 130VAC (Vmax). The device is able to absorb overvoltage during positive or negative transient conditions and provide protection against voltage spikes.

The B72250L0271K102 is widely used in various power supplies, telecommunications and industrial automation applications. It is suitable for use in battery backed power supplies, point of load supplies, digital signal processor (DSP)/microcontroller based systems, as well as microcontrollers and digital logic probes/signal conditioning.

The working principle behind the B72250L0271K102 is based on Metal Oxide Varistor technology. During a normal operating condition, the device passes current in both directions. During surge events, the device changes from a low resistance to a high-resistance state, which helps to mitigate the surge and protect the power system from overvoltage. This occurs when the current passes through the internal dielectric material which momentarily heats up and causes a decrease in resistance. This is known as “Non-Linear Resistance” and is what makes the device so effective in protecting circuits and systems from overvoltage and surge events.

The B72250L0271K102 is an ideal device for applications requiring protection from transient voltage surges. It has a low profile design with extended storage temperature capability, and offers high surge current and clamping voltage capabilities. It is suitable for 15W power supplies and above, as well as other applications that require a low-cost transient voltage protection solution.
