TVS Diode Arrays (SPA® Diodes) Datasheet
SC7538-08UTG
0.3pF Diode Array, Low Capacitance ESD Protection
RoHS Pb
Description
The SC7538 integrates 8 channels of ultra low capacitance rail-to-
rail diodes and an additional zener diode to provide protection for
electronic equipment that may experience destructive electrostatic
discharges (ESD). This robust device can safely absorb repetitive
ESD strikes above the maximum level maximum level, 8kV
contact discharge, as specified in the international standard IEC
61000-4-2, without performance degradation standard ( 8kV
contact discharge) without performance degradation. The
extremely low loading capacitance also makes it ideal for
protecting high speed signal pins such as V-By-One, HDMI,
USB3.0, USB2.0, and IEEE 1394.
