Note 2: 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).

Handling Precaution
1)
The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded,even
for a moment. Do not exceed any of these ratings. The following are the general derating methods that we
recommend when you design a circuit with a device.
P:
We recommend that the worst case power dissipation be no greater than 50% of the
absolute maximum rating of power dissipation. Carry out adequate heat design.
PRSM:
We recommend that a device be used within the recommended area in the figure,
PRSM-tw.
Tj:
Derate this rating when using a device in order to ensure high reliability.
We recommend that the device be used at Tj of below 120°C.
2)
Thermal resistance between junction and ambient fluctuates depending on the device’s mounting condition.
When using a device, design a circuit board and a soldering land size to match the appropriate thermal
resistance value.
3)
Please refer to the Rectifiers databook for further information.
