SR2.8_10 Datasheet, PDF (1/6 Pages) Protek Devices – ultra low capacitance steering diode/TVS array
Only One Name Means ProTek’Tion™
ultra low capacitance steering diode/TVS array
SR2.8 - SR3.3
SOT-143 package
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 microam-
pere. 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.
