DEVICES FOR BI-DIRECTION APPLICATIONS
(“_X” denotes revision code e.g. A, B, ...)
For bi-directional devices use CA suffix (e.g. P4SMA10CA).
Electrical characteristics apply in both directions.
Terminals: matte tin plated leads, solderable per
J-STD-002 and JESD 22-B102
E3, M3, HE3, and HM3 suffix meets JESD 201 class 2
whisker test
Polarity: for uni-directional types the band denotes cathode
end, no marking on bi-directional types
