TVS - Diodes

---

A Transient Voltage Suppressor (TVS) diode is a sophisticated form of a standard diode. It is designed to protect sensitive electronic devices against surges in electrical energy such as lightning strikes, power outages, and voltage spikes. It works in a unique way; it senses voltage increases and then closes the circuit to clamp the voltage down.The SD05C-7 is a common type of TVS diode. This diode can operate with reverse standoff voltages ranging from 5.0V to 7.0V; and has a maximum clamping voltage of 11.0V. The operating temperature range is -55 to 125°C. It is typically used in consumer electronics, automotive applications, and telecommunications. It also provides a high level of tolerance to radiation, ensuring the stability of its operation.The SD05C-7 is designed to work in a single-phase environment, and can absorb up to a maximum peak pulse current of 1.4A. It is constructed using a silicon Zener diode with an avalanche layer. It has common cathode and a diode configuration, and has a low capacitance rating of 4pF. In order to work properly, it must be connected to a resistor, which should be 2.2~4.7Ω for the protection of the TVS diode. When a voltage spike occurs, the TVS diode will quickly sense the voltage increase and act by either breaking the circuit or clamping the voltage down and shifting it into a safe operating range. It should not be confused with an arrester, which can also protect applications from power surges. An arrester will break the circuit and release its charge before the surge can reach the application.When connected into a circuit, the SD05C-7 acts as a voltage clamp. It prevents voltage from passing through it instead of breaking the circuit, which in turn saves the components connected to it from damage due to power surges, overvoltages, or ESD. It also dissipates the energy of the surge and clamps it to a safe level, thus ensuring that the connected components remain protected.The TVS diode can also be used to protect against ElectroStatic Discharge (ESD), which can occur due to contact with a charged surface. The ESD can be absorbed by the diode, and can protect the components against possible damage.The SD05C-7 is an important and widely used device that helps to protect sensitive parts from external damage caused by power surges or ESD. Its versatility and wide range of applications make it an invaluable addition to any circuit that needs to remain safe from temporary voltage surges.
