Only One Name Means ProTek’Tion™
The SR series oers 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 eects of Electrostac Discharge (ESD) and
Electrical Fast Transients (EFT).
The SR series is ideal for low voltage circuit applicaons. The leakage current for the SR2.8 is less than 1.0 microam-
pere. The low capacitance of the steering diode allows the designer to protect high speed data applicaons. The
small SOT-143 package, with four leads reduces the internal lead inductance for low overshoot voltage during fast
front me transient events, such as ESD. This device meets the IEC 61000-4-2 and IEC 61000-4-4 requirements.
