Handling Precaution

1) The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded,even

for a moment. Do not exceed any of these ratings. 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

absolute maximum rating of power dissipation. Carry out adequate heat design.

We recommend that a device be used within the recommended area in the figure,

Derate this rating when using a device in order to ensure high reliability.

2) Thermal resistance between junction and ambient fluctuates depending on the device’s mounting condition.

When using a device, design a circuit board and a land pattern to match the appropriate thermal resistance

value.

3) Please refer to the Rectifiers databook for further information.
