The SMF7V0A-E3-08 is a common type of TVS Diode, which is a shunt component designed to protect circuit power supplies from overvoltage or high current events. It is a low-capacitance, low-capacitance-to-drain current, high-integrity, and low-leakage solution designed to safely meet the surge protection needs of a wide range of applications.TVS diodes provide a wide range of protection with a variety of features. They offer robust protection from over-voltage, under-voltage, over-current, and excess heat. TVS diodes are made with robust components and can withstand transient-voltages up to 5kV, with a peak clamp current of 10kA, and working temperatures of -40˚C to 150˚C.The SMF7V0A-E3-08 is specifically designed to protect against electromagnetic interference (EMI) and electrostatic discharge (ESD) throughout a broad frequency range. It has a low capacitance of 8pF, a low capacitance-to-drain current ratio of 0.7pF/A, and a high integrity of 8.0A (10-5A/W for a case temperature of 25˚C).Common applications of the SMF7V0A-E3-08 include one-time wireless avionics systems, ethernet hubs and switches, and industrial equipment requiring protection from voltage transients, power spikes, and EMI/ESD. The diode is often found in high performance systems where an increased resistance or capacitance would compromise operation.TThe SMF7V0A-E3-08 TVS diode works by clamping the input voltage. When a voltage spike higher than the clamp voltage is encountered, the power supply is temporarily reset, and the diode is then enabled. This prevents waveform distortion that could lead to catastrophic system failure or longer-term damage.The SMF7V0A-E3-08 has several advantages over other types of protection components. Its low capacitance, low capacitance-to-drain current ratio, and high integrity are designed to provide the necessary protection while still allowing for effective and reliable operation. In addition, due to its small size, it can be used in very small spaces and does not require a large footprint.TVS diodes are an essential protection element in any high-performance electronic system. The SMF7V0A-E3-08 is designed to provide the necessary protection while still allowing for controlled and efficient operation. Its low capacitance, low capacitance-to-drain current ratio, and high integrity make it a reliable and cost-effective solution for a variety of applications.
