DF3A8.2LFE
TOSHIBA Diodes For Protecting Against ESD
Epitaxial Planar Type
DF3A8.2LFE
Product for Use Only as Protection against Electrostatic
Discharge (ESD)
*
This product is for protection against electrostatic discharge (ESD)
only and is not intended for any other usage, including without
limitation, the constant voltage diode application.
•
Because two devices are mounted on an ultra compact package, it is
possible to allow reducing the number of the parts and the mounting
cost.

absolute maximum ratings.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
