Overview

PSRDAxx-4A Series

The PSRDAxx-4A Series are low capacitance multi-line steering diode/transient voltage suppressor arrays that provides board level protection for standard TTL and CMOS bus line applications against the damaging effects of ESD, tertiary lightning and switching transients. The PSRDAxx-4A Series has a peak pulse power rating of 500 Watts for an 8/20µs waveshape. This device series meets the IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 requirements.
