SR2.8_10

05167 Only One Name Means ProTek’Tion™ SR2.8 - SR3.3 ultRa low caPacitance SteeRing diode/tVS aRRay deScRiPtion The SR series offers two low voltage (2.8V & 3.3V) and low capacitance steering diode TVS arrays. This series is designed to protect two line pair or four data/transmission lines from the effects of Electrostatic Discharge (ESD) and Electrical Fast Transients (EFT). The SR series is ideal for low voltage circuit applications. The leakage current for the SR2.8 is less than 1.0 microampere. The low capacitance of the steering diode allows the designer to protect high speed data applications. The small SOT-143 package, with four leads reduces the internal lead inductance for low overshoot voltage during fast front time transient events, such as ESD. This device meets the IEC 61000-4-2 and IEC 61000-4-4 requirements.
