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.

account designing a device at low temperature.

Carry out adequate heat design. If you can’t design a circuit with excellent heat radiation, set the

This rating specifies the non-repetitive peak current in one cycle of a 50-Hz sine wave, condition angle 180.

Therefore, this is only applied for an abnormal operation, which seldom occurs during the lifespan of the device.

We recommend that a device be used at a Tj of below 100°C under the worst load and heat radiation conditions.

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.
