Devices for Bidirectional Applications
For bi-directional, use C or CA suffix for types 1.5KE6.8 thru types 1.5KE440
(e.g. 1.5KE6.8C, 1.5KE440CA). Electrical characteristics apply in both directions.

* Bidirectional versions are UL approved under component across the line protection, ULV1414 file number E108274 (1.5KE200CA, 1.5KE220CA)
+ Underwriters Laboratory Recognition for the classification of protectors (QVGQ2) under the UL standard for safety 497B and file number E136766
for both uni-directional and bi-directional devices
Application
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 watts for one millisecond. The response time of TVS diode clamping action is
effectively instantaneous (1 x 10
-9
seconds bidirectional); 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.
