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 and
telecommunication.
MECHANICAL DATA
Case:
DO-214AC (SMA)
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)
Polarity:
For unidirectional types the band denotes
cathode end, no marking on bidirectional types
DEVICES FOR BIDIRECTION APPLICATIONS
For bidirectional devices use CA suffix (e.g. P4SMA10CA).
Electrical characteristics apply in both directions.
