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.
VRRM:
We recommend that the worst case voltage, including surge voltage, be no greater than 80% of the
maximum rating of VRRM for a DC circuit and be no greater than 50% of that of VRRM for an AC
circuit. VRRM has a temperature coefficient of 0.1%/°C. Take this temperature coefficient into
account designing a device at low temperature.
IF(AV):
We recommend that the worst case current be no greater than 80% of the maximum rating of IF(AV).
Carry out adequate heat design. If you can’t design a circuit with excellent heat radiation, set the
margin by using an allowable Tamax-IF(AV) curve.
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.
Please refer to the Rectifiers databook for further information.
