Weight: 0.013 g (typ.)
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
Schottky barrier diodes have reverse current characteristics compared to other diodes.
There is a possibility SBD may cause thermal runaway when it is used under high temperature or high voltage.
Please take forward and reverse loss into consideration during design.
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
:
Use this rating with reference to the above. 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
F(AV)
and T
j
be below 120°C. When using this device, take the margin into consideration by using an
allowable Tamax-I
F(AV)
curve.
This rating specifies the non-repetitive peak current. This is only applied for an abnormal operation,
which seldom occurs during the lifespan of the device.
Derate this rating when using a device in order to ensure high reliability. We recommend that the device
be used at a T
j
of below 120°C.

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.
