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).
Note 1: Mounted on an FR4 board.

Usage Considerations
• Schottky barrier diodes (SBDs) have reverse leakage greater than other types of diodes.
This makes SBDs more susceptible to thermal runaway under high-temperatur...
