transients induced by inductive load switching and
lighting on ICs, MOSFET, signal lines of sensor units
for consumer, computer, industrial, automotive and
telecommunication.
MECHANICAL DATA
Case: DO-214AB (SMC)
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
DO-214AB (SMC)
DEVICES FOR BIDIRECTION APPLICATIONS
For bidirectional devices use CA suffix (e.g. 1.5SMC220CA).
Electrical characteristics apply in both directions.
