RATING AND CHARACTERISTIC CURVES FOR SMDA05C-8 THRU SMDA24C-8
*Application note: Due to the topology of the SMDA array the VRWM and V (BR) specifications also
apply to the differential voltage between any two data line pins. Hence the SMDA12C-8 is
designed to “see” a maximum voltage excursion of ± 6 volts between any two data lines.
