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 denote the absolute maximum ratings, which are rated values and must not be
exceeded during operation, even for an instant. 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 thefigure,
PRSM-tw.
Tj
: Derate this rating when using a device in order to ensure high reliability.
We recommend that the device be used at a 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.
