SMDA03LC - SMDA24LCC
500 WATT MULTI-LINE LOW CAPACITANCE TVS ARRAY
DESCRIPTION
The SMDAxxLC and SMDAxxLCC Series are low capacitance multi-line transient voltage suppressor arrays that provides
board level protection for standard TTL and MOS bus line applications against the damaging effects of ESD, tertiary
lightning and switching transients.
The SMDAxxLC/LCC 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.
