Handling Precautions
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 we recommend for
designing a circuit using 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 no greater than 50% of that of V_RRM for an AC circuit.
V_RRM has a temperature coefficient of 0.1%/℃. Be sure to take this temperature coefficient into account
when designing a device for use 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 sufficient heat design. If it is not possible to design a circuit with excellent heat radiation, set
a margin by using an allowable Tamax- I_F (AV) curve.
This rating applies only to a strobe flash circuit. We recommend that the worst case current be kept within the
absolute maximum rating of IFRM. The total number of repetitive currents should not exceed 7000 within the
lifespan of the device.
This rating specifies the non-repetitive peak current in one cycle of a 50 Hz sine wave, condition angle 180°.
Therefore the rating applies only to abnormal operation, which seldom occurs during the lifespan of a device.
For this device, we recommend a Tj of below 120℃ under the worst load and heat radiation conditions.
Thermal resistance between junction and ambient fluctuates depending on the mounting condition of the device.
When using the device, be sure to design the circuit board and soldering land size to match the appropriate thermal
resistance value.
