Weight: 0.023 g (typ.)
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
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.
