MECHANICAL DATA
The devices listed in this document take the
following physical form:
Diameter
Height
1.5KE TVS Cells: Assembled with 118mil Hex Die
Max. Height 65mil. Max. Dia 50mil
All dice are passivated either glass or
These cell TVS devices are specially designed for TVS
modules and hybrid circuit applications. The benefit
of this package is less space and easier assembly
Users should be cautioned that the assembled
modules must be properly protected to avoid the
glass or Si02 passivated die damage.
DEVICES FOR BIPOLAR APPLICATIONS
For Bidirectional 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.
