The TVS diodes, model PTVS7V0S1UTR,115, provide an effective way to protect a circuit from transient voltage spikes. The overvoltage protection circuit is designed to work by creating a low-impedance path between the power input and ground. This creates a short that dissipates any overvoltage before it can reach the components in the circuit.

Application Field

TvS diodes are often used in circuits involving AC/DC conversion, such as protection circuits for power supplies, motor drives, and battery chargers. In addition, this type of diode is often used in communications and networking applications, such as Ethernet cables and CAT5, as well as in automotive, military and aerospace circuits.

Working Principle

TVS diodes use avalanche breakdown technology to protect against an overvoltage condition. When the input voltage reaches the breakdown voltage of the diode, the diode will increase its current flow dramatically, reducing the voltage to the point that the circuit is protected. This is known as the breakdown resistance and can be tailored based on the specific circuit needs.

In other words, when a high voltage is encountered by the TVS diode, the diode will start to conduct and dissipate the excess voltage as heat. This allows the voltages in the circuit to remain below the rated breakdown voltage and keeps the components safe.

Conclusion

The PTVS7V0S1UTR,115 TVS diodes provide a reliable method of protecting a circuit from high transient voltage surges. With their avalanche breakdown technology, these diodes can save circuits from catastrophic failure while providing a low-impedance path to help dissipate the transient energy. As a result, these diodes are often used in a variety of applications such as AC/DC conversion circuits, Ethernet cables, and automotive and military applications.
