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-15 (DO-204AC)
Molded epoxy over passivated chip
Molding compound meets UL 94 V-0 flammability rating
Base P/N-E3 - RoHS compliant, commercial grade
Base P/NHE3 - RoHS compliant, AEC-Q101 qualified
Terminals:
matte tin plated leads, solderable per
J-STD-002 and JESD 22-B102
E3 suffix meets JESD 201 class 1A whisker test, HE3 suffix
meets JESD 201 class 2 whisker test
Polarity:
for uni-directional types the color band denotes
cathode end, no marking on bi-directional types
DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional types, use CA suffix (e.g. SA5.0CA,
SA170CA).
Electrical characteristics apply in both directions.
