Note: Using continuously under heavy loads (e.g. the application of high
temperature/current/voltage and the significant change in
temperature, etc.) may cause this product to decrease in the
reliability significantly even if the operating conditions (i.e.
operating temperature/current/voltage, etc.) are within the
absolute maximum ratings.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test report
and estimated failure rate, etc).

Handling Precaution
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 that we recommend
when you design a circuit with a device.
VRRM: Because this device is developed for use in a strobe flash, we recommend that peak voltage of set’s
apply voltage that generates pulse be no greater than 80% of the absolute maximum rating of VRRM
and DC supply voltage be no greater than 400 V. 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 absolute 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.
IFSM: 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.
Tj: We recommend that a device be used at a Tj of below 100°C under the worst load and heat radiation
conditions.
Please refer to the Rectifiers databook for further information.
