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: Measured with a 10 ms pulse.
Note 2: Mounted on a glass epoxy circuit board of 20 mm × 20 mm, Pad dimension of 4 mm × 4 mm.

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-temperature and high-voltage conditions. Thus, both
forward and reverse power losses of SBDs should be considered for thermal and safety design.
