DF3A8.2LFU TOSHIBA Diodes for Protecting against ESD Epitaxial Planar Type DF3A8.2LFU Product for Use Only as Protection against Electrostatic Discharge (ESD) Unit: mm * 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.) Absolute Maximum Ratings (Ta = 25°C) Characteristics Symbol Rating Unit Power dissipation P 100 mW Junction temperature Tj 125 °C Tstg −55 ~ 125 °C Storage temperature range Note: Using continuously under heavy loads (e.g. the application of high JEDEC ― temperature/current/voltage and the significant change in JEITA ― temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. TOSHIBA 1-2P1A operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Weight: 0.006 g (typ.) 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).
