TOSHIBA Diodes for Protecting against ESD
DF3A6.2LFV
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.
• Low terminal capacitance: C

−55 to 150 °C
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).
*: Mounted on FR4 board (25.4 mm × 25.4 mm × 1.6 mmt)
