TOSHIBA Diodes for Protecting against ESD Epitaxial Planar Type
DF3A8.2LFV
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 in an ultra-compact package enables a
reduction in the number of parts and in the mounting cost.

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).
