Ordering Information
The part numbers shown are for single diodes. When
ordering diodes in common cathode pairs add suffix
“CK.” For example, MA4ST079CK specifies model num-
ber MA4ST079 as a common cathode pair. To order parts
on tape and reel add suffix T/R to the end of the part
number. i.e. MA4ST079-T/R
