3.6 °C/W
*MTTF - median time to failure for wear-out failure mode (30%ldss
degradation) which is determined by the technology reliability. Refer to
product qualification report for FIT (random) Failure rate.
Operation of this device beyond any one of these limits may cause permanent
damage. For reliable continuous operation, the device voltage and current
must not exceed the maximum operating values specified in the table on page
two.
Bias Conditions should also satisfy the following expression:
PDISS < (TJ – TC) / RTH J-C and TC = TCASE

Caution! ESD sensitive device.
Exceeding any one or a combination of the Absolute Maximum Rating conditions may
cause permanent damage to the device. Extended application of Absolute Maximum
Rating conditions to the device may reduce device reliability. Specified typical perfor-
mance or functional operation of the device under Absolute Maximum Rating condi-
tions is not implied.
