MECHANICAL DATA
Case: DO-214AC (SMA)
Molding compound meets UL 94 V-0 flammability
rating
Base P/N-E3 - RoHS compliant, commercial grade
Base P/NHE3 - RoHS compliant, high reliability/
automotive grade (AEC Q101 qualified)
Terminals: Matte tin plated leads, solderable per
J-STD-002 and JESD22-B102
DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional devices use CA suffix (e.g.
P4SMA10CA).
Electrical characteristics apply in both directions.
E3 suffix meets JESD 201 class 1A whisker test, HE3
suffix meets JESD 201 class 2 whisker test
Polarity: For uni-directional types the band denotes
cathode end, no marking on bi-directional types
