SMDA03-7TR is a current protected TVS diode array integrated circuit developed by Littelfuse. This device is suitable for 15kV ESD protection within a very small 8-SOIC package. The device is particularly suitable for protecting high speed communications ports, as it features fast-response times and low capacitance.The SMDA03-7TR is designed with a low capacitance, low-clamping transient voltage protection by combining a series array of 7 discrete TVS diodes and guard bands into a single integrated circuit. It offers excellent protection for applications which require very high-speed transient protection with reduced EMI/RFI noise.The SMDA03-7TR can be used to protect peripheral ports such as RS-485, Ethernet, USB, Video, and Audio-Video. It is ideal for use in low-speed and high-speed consumer electronics devices, computers, servers, peripherals, telecom/datacom equipment, and other applications where high ESD protection is required for data line protection.The working principle of the SMDA03-7TR is based on the Zener based TVS diode array. When a high-energy transient event occurs, such as ESD, the reverse bias breakdown voltage of the Zener diode is triggered, providing the necessary clamping action. The internal guard bands, which are designed to prevent device over-stress, are placed between the Zener diodes to prevent the transient energy from flowing between diodes. The guard bands also provide extra linearity during clamping.The SMDA03-7TR features a low leakage current and has a maximum rated continuous power dissipation of 1.0W at Ta=25°C. The device has a high-speed ESD protection of up to 15kV Human Body Model (HBM) per JESD22-A114, and 8kV contact-discharge ESD protection (CDP) per JESD22-C101.In addition, the SMDA03-7TR features an extended temperature range from -55°C to +125°C for reliable operation during extreme temperature conditions. The SMDA03-7TR is compliant to current environmental requirements such as RoHS and is available in 8-SO packages for space-constrained applications.Overall, the SMDA03-7TR is a high-performance ESD protection device for high-speed communications ports which offers excellent protection with low capacitance and fast-response times. It is suitable for a wide variety of low- speed and high-speed consumer electronics applications including RS-485, Ethernet, USB, Video, and Audio-Video.
