Handling Precaution

1) 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.

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.

: 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 soldering land size to match the appropriate thermal

resistance value.

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