Specifications

The SP3071EMN has a typical clamping voltage of 7V at a specified surge current. Its capacitance is typically around 0.5pF, ensuring minimal signal degradation. The device is designed to withstand ESD strikes up to ±30kV (contact and air discharge) according to IEC 61000-4-2. It also provides protection against EFT events as per IEC 61000-4-4 and surge events per IEC 61000-4-5. The device is usually available in a small MSOP-10 package. The operating temperature range is typically from -40°C to +85°C. The SP3071EMN helps to protect downstream components from overvoltage conditions, increasing the overall robustness of the electronic system.
