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.

7. Usage Considerations

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.
