Handling Precaution
1) The absolute maximum ratings denote the absolute maximum ratings, which are rated values that must not be
exceeded during operation, even for an instant. The following are the general derating methods that we recommend for
designing a circuit incorporating this device.
V_RRM: We recommend that the worst case voltage, including surge voltage, be no greater than 80% of the absolute
maximum rating of V_RRM for a DC circuit and be no greater than 50% of that of V_RRM for an AC circuit.
V_RRM has a temperature coefficient of 0.1%/°C. Take this temperature coefficient into account designing a
device at low temperature.
I_F(AV): We recommend that the worst case current be no greater than 80% of the absolute maximum rating of I_F(AV).
Carry out adequate heat design. If you can’t design a circuit with excellent heat radiation, set the margin by using
an allowable Ta max-I_{F (AV)} curve.
I_FSM: This rating specifies the non-repetitive peak current. This is only applied for an abnormal operation, which seldom
occurs during the lifespan of the device.
T_j: Derate this rating when using a device in order to ensure high reliability.
We recommend that a device be used at a T_j of below 120°C.
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.
