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).

Handling Precaution
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.
V
RRM
:
We recommend that the worst case voltage, including surge voltage, be no greater than 80% of the
absolute maximum rating of V
RRM
for a DC circuit and be no greater than 50% of that of V
RRM
for
an AC circuit. V
RRM
has a temperature coefficient of 0.1%/°C. Take this temperature coefficient into
account designing a device at low temperature.
We recommend that the worst case current be no greater than 80% of the absolute maximum rating
of I
O
. Carry out adequate heat design. If you can’t design a circuit with excellent heat radiation, set
the margin by using an allowable Tamax-I
O
curve.
I
O
:
This rating specifies the non-repetitive peak current in one cycle of a 50-Hz sine wave, condition angle 180.
Therefore, this is only applied for an abnormal operation, which seldom occurs during the lifespan of the device.
We recommend that a device be used at a Tj of below 120°C under the worst load and heat radiation conditions.
Please refer to the Rectifiers databook for further information.
