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 performance or
functional operation of the device under Absolute
Maximum Rating conditions is not implied.
* MTTF – median time to failure for wear-out failure mode (30% IDSS degradation) which is determined by the technology process 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 above.
**Thermal resistance assumes AuSn die attach on 1.5mm thick CPC carrier similar to Kyocera A1933. User will need to define this specification
in the final application and ensure bias conditions satisfy the following expression: PDISS < (TJ – TC) / RTH J-C and TC = TCASE to maintain maximum operating
junction temperature at MTTF.
