Package Outline
Notice
●
●
Product is intended for use in general electronics applications.
Product should be worked less than the ratings; if exceeded, may cause permanent damage. or introduce latent failure
mechanisms.
The absolute maximum ratings are rated values and must not be exceeded during operation. The following are the general
derating methods you design a circuit with a device.
I
F(AV)
: We recommend that the worst case current be no greater than 80% .
I
FSM
: This rating specifies the non-repetitive peak current. This is only applied for an abnormal operation, which the general
during the lifespan of the device.
T
J
:
Derate this rating when using a device in order to ensure high reliability. We recommend that the device be used at
a T
J
of below 125°C.
