TVS-Diodes

TVS (Transient Voltage Suppressor) diodes are specially designed semiconductor devices that are specifically created for the purpose of providing overvoltage protection. They are used to protect electronic circuits from the effects of large electrical surges caused by lightning strikes, static energy, and other sources. There are several types of TVS diodes available on the market, including TVS505SM.

TVS505SM Application Field

TVS505SM is a common type of TVS diode used in applications which require overvoltage protection. It is suitable for systems subjected to transients in the range of 4V to 24V, with 1500W peak pulse power at 8/20μs pulse duration. It is also designed to protect against faster transients.The TVS505SM is used in many applications, such as consumer electronics, automotive electronics, industrial electronics, and other telecom systems.

TVS505SM Working Principle

TVS505SM diodes operate on the principle of voltage clamping. When a higher voltage is applied, the voltage across the two terminals of the device is clamped at the rated voltage. This limits the amount of current that can flow through the device and protects the system from an overvoltage condition. When the surge energy is absorbed and dissipated, the voltage across the TVS505SM diode returns to normal, allowing the system to resume normal operations.

TVS505SM Benefits

One of the advantages of using TVS505SM diodes in overvoltage protection applications is their low cost. They are much less expensive than other types of surge protection, such as metaloxides and gas tubes. TVS505SM diodes are also highly reliable, as they can handle transients up to 8/20µs in pulse duration, and are highly reliable under severe heat and vibration. Moreover, they have a long lifespan and are maintenance-free.

Conclusion

TVS505SM diodes are one of the most popular types of TVS diodes used for overvoltage protection. They are relatively inexpensive, maintenance-free, and highly reliable. They are suitable for a range of application fields, such as consumer electronics, automotive electronics, industrial electronics, and other telecom systems. The operating principle of TVS505SM is voltage clamping, which limits the amount of current that can flow through the device and protects the system from an overvoltage condition.
