MECHANICAL DATA
Case: DO-204AC, molded epoxy over passivated chip
Epoxy meets UL 94V-0 flammability rating
Terminals: Matte tin plated leads, solderable per
J-STD-002B and JESD22-B102D
E3 suffix for commercial grade, HE3 suffix for high
reliability grade (AEC Q101 qualified)
DEVICES FOR BIDIRECTION APPLICATIONS
For bidirectional types, use
(e.g. SA5.0C, SA170CA).
C
or CA suffix
Electrical characteristics apply in both directions.
Polarity: For unidirectional types the color band
denotes cathode end, no marking on bidirectional
types
