TOSHIBA Diodes for Protecting against ESD Epitaxial Planar Type
DF3A8.2FU
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.
The mounting of two devices on an ultra-compact package allows the
number of parts and the mounting cost to be reduced.
Low terminal capacitance: CT = 5.0 pF (typ.)

Note: Using continuously under heavy loads (e.g. the application of high
temperature/current/voltage and the significant change in
temperature, etc.) may cause this product to decrease in the
reliability significantly even if the operating conditions (i.e.
operating temperature/current/voltage, etc.) are within the 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).
