TVS - Varistors, MOVs
The B72530T1140S272 is a Transient Voltage Suppressor (TVS) designed to initially clamp and absorb high voltage, high-energy transients. Depending on the application it’s designed for, it can function as a varistor, Metal Oxide Varistor (MOV), or an over-voltage suppressor.The initial use of this model is to protect sensitive electronic circuits from potentially damaging transients by clamping voltages at a safe, acceptable level. In the event of a power surge or transient voltage, the B72530T1140S272 will absorb the excess voltage spike and clamp it to the protection voltage, thereby preventing the voltage spike from damaging the equipment.
Application Field of B72530T1140S272
The B72530T1140S272 is most commonly used as a metal oxide varistor or an over-voltage suppressor. It can be used in a variety of applications, including:
- Computer equipment
- Uninterruptible power supplies (UPS)
- Automotive electronics
- Industrial electronics
- Telecommunications
- Consumer electronics
- Aviation
- Medical electronics
- Power supplies
- Automatic train control systems
The B72530T1140S272’s surge rating makes it ideal for applications wherein transient protection is needed. It’s able to dissipate up to 600W of power for an 8-μs pulse or 150W for a 20-μs pulse without performance degradation. This makes it an ideal choice for applications that deal with high-energy surges and high-voltage transients, such as automotive electronics, avionics, medical equipment, and consumer electronics.
Working Principle of B72530T1140S272
The working principle of the B72530T1140S272 is simple: it absorbs the transient voltage spike and clamps it to a safe, acceptable level. The device consists of two electrodes, a ceramic body, and a metal oxide varistor (MOV).
When there is no current flowing through the device, the MOV acts as an open circuit and there is no voltage across the electrodes. However, when a transient voltage spike occurs, the MOV begins to conduct current. This causes the voltage across the electrodes to rise. The ceramic body is designed to absorb the excess energy and convert it into heat. This, in turn, prevents the voltage spike from reaching the sensitive electronic components of the application.
Once the energy has been dissipated, the MOV switches back to its open-circuit state and the voltage across the electrodes goes back to zero. This cycle can repeat multiple times, thus protecting the device from a wide range of transient voltages.
Conclusion
The B72530T1140S272 is a versatile device designed to protect sensitive electronic circuits from potential damage caused by transient voltage spikes. It can function as a varistor, MOV, or over-voltage suppressor, making it suitable for a wide range of applications. Moreover, its surge rating makes it ideal for applications that require high-energy, high-voltage transient protection.
