DEVICES FOR BIDIRECTION APPLICATIONS
For bidirectional types, use CA suffix (e.g. 1.5KE220CA)
Electrical characteristics apply in both directions.
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.
MECHANICAL DATA
Case: molded epoxy body over passivated junction
Molding compound meets UL 94 V-0 flammability rating
Base P/N-E3 - RoHS compliant, commercial grade
Base P/NHE3_X - RoHS compliant, and AEC-Q101 qualified
(“X” denotes revision code e.g. A, B, ...)
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
Note
• 1.5KE250A to 1.5KE540A are commercial grade only
• Bidirectional is available from 1.5KE6.8CA to 1.5KE220CA only
Polarity: for unidirectional types the color band denotes
cathode end, no marking on bidirectional types

APPLICATION NOTES
• This series of Silicon Transient Suppressors is used in
applications where large voltage transients can
permanently damage voltage-sensitive components.
• The TVS diode can be used in applications where
induced lightning on rural or remote transmission
lines presents a hazard to electronic circuitry
(ref: R.E.A. specification P.E. 60).
• This Transient Voltage Suppressor diode has a pulse
power rating of 1500 W for 1 ms. The response time of
TVS diode clamping action is effectively instantaneous
(1 x 10-9 s bi-directional); therefore, they can protect
integrated circuits, MOS devices, hybrids, and other
voltage sensitive semiconductors and components. TVS
diodes can also be used in series or parallel to increase
the peak power ratings.
