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
