Unidirectional, bidirectional
SMA (DO-214AC)
(“_X” denotes revision code e.g. A, B, ...)
Terminals: matte tin plated leads, solderable per
J-STD-002 and JESD 22-B102
DEVICES FOR BIDIRECTION APPLICATIONS
E3, M3, HE3, and HM3 suffix meets JESD 201 class 2
whisker test
For bidirectional use CA suffix (e.g. SMAJ10CA).
Electrical characteristics apply in both directions.
Polarity: for unidirectional types the band denotes cathode
end, no marking on bidirectional types
TYPICAL APPLICATIONS
Use in sensitive electronics protection against voltage
transients induced by inductive load switching and lighting
on ICs, MOSFET, signal lines of sensor units for consumer,
computer, industrial, automotive, and telecommunication.
