TOSHIBA Diodes for Protecting against ESD
DF5A3.3F
Diodes for Protecting against 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.
z The mounting of four devices on an ultra-compact package allows the
number of parts and the mounting cost to be reduced.

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).
