TVS - Varistors, MOVs help ensure efficient and reliable electrical power distribution, protection and conditioning, and successively reduce power quality risks. The B72500T5170S260 is a member of this group, one specifically chosen for use in temperature-sensitive applications.

The B72500T5170S260 is available in a variety of packages suitable for a variety of applications. The device utilizes a junction diode connected between the anode and the cathode and lies in series with the output line, creating a T-network for the protection of power supplies. The device is designed to protect sensitive front-end circuits from excessive transient voltages and reduce interference effects to allow proper operation.

It is suitable for use in a variety of sectors such as medical, computer, communication, military, industrial control and home appliances, and can be used as a power supply line protection common in all circuit boards. For instance, it can be used in medical equipment, such as anesthesia instruments, defibrillators, catheters and infusion pumps in hospitals; or for telecom and data processing equipment used in tester and routers in telephone systems.

The B72500T5170S260 is available in a variety of voltages and is both temperature and frequency dependent. It is a combination of two devices in one, an inversely poled bidirectional transient voltage suppressor (TVS) and a unidirectional Metal Oxide Varistor (MOV). The key behind its efficient working is the variable resistor, MOV. It diverts the high-current or high-voltage pulse to ground by its forward resistance and maintains a specific resistance inversely proportional to the voltage (lower resistance at the higher voltage) which directs the overvoltage to ground and thus protects the equipment.

The B72500T5170S260 is specifically designed to protect heavy-load equipment in temperature-sensitive environments. It is able to protect the equipment from transient voltages and maintain the required circuit performance at low temperature. The device can survive noxious transient impulses up to 2500V without damage to the connected load. The ESD transient clamping function also helps protect against electro-static discharge (ESD).

The device provides overload protection of the PC board power rails while reducing conducted interference on the connected circuit. The MOV is able to protect devices from excessive electrical surges through rapid discharge of the transient energy. The TVS on the other hand provides connection to the ground during over-voltage conditions when the MOV has reached its breakdown voltage. Thus, the device helps to protect the connected system from lightning strikes, surges, and various other electrical interference.

In conclusion, the B72500T5170S260 is designed to protect a wide range of temperature-sensitive load applications such as medical equipment, telecom and data processing equipment, telecommunications systems, and home appliances. It integrates both a transient voltage suppressor and a Metal Oxide Varistor for overload protection, low dynamic impedance, and ESD transient protection. It also provides high current and high surge capability at low operating temperatures.
