Handling Precaution
The 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 maximum
rating of power dissipation. Carry out adequate heat design.
We recommend that a device be used within the recommended area in the figure, P
RSM
-tw.
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.
P
RSM
:
T
j
:
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.
