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 when designing a circuit incorporating this device.
VRRM: We recommend that the worst case voltage, including surge voltage, be no greater than 80% of the
absolute maximum rating of VRRM for a DC circuit and no greater than 50% of that of VRRM for an AC
circuit. VRRM has a temperature coefficient of 0.1%/℃. Take this temperature account coefficient
into when designing a device for operation at low temperatures.
IF(AV): We recommend that the worst-case current be no greater than 80% of the absolute maximum rating of
IF(AV) and that the worst-case junction temperature, Tj, be kept below 120℃. When using this device,
allow margins, referring to the Ta(max) - IF(AV) curve.
IFSM: This rating specifies peak non-repetitive forward surge current. This only applies to an abnormal
operation, which seldom occurs during the lifespan of a device.
Tj: Derate device parameters in proportion to this rating in order to ensure high reliability.
We recommend that the junction temperature (Tj) of a device be kept below 120℃.
2) Thermal resistance (junction-to-ambient) varies with the mounting conditions of a device on a circuit board. An
appropriate thermal resistance value should be used, considering the heat sink, circuit board design and soldering
land size.
