DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional types, use CA suffix (e.g. P4KE440CA).
Electrical characteristics apply in both directions.
Terminals: matte tin plated leads, solderable per
J-STD-002 and JESD 22-B102
E3 suffix meets JESD 201 class 1A whisker test, HE3 suffix
meets JESD 201 class 2 whisker test
