Using continuously under heavy loads (e.g. the application of
TOSHIBA

high temperature/current/voltage and the significant change in
temperature, etc.) may cause this product to decrease in the
Weight: 0.023 g (typ.)
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.
I
F(AV)
: We recommend that the worst case current be no greater than 80% of the absolute maximum rating of I
F(AV)
.
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
F (AV)
curve.
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.
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.
Please refer to the Rectifiers databook for further information.
