Caution! ESD sensitive device.

RoHS (Restriction of Hazardous

Substances): Compliant per EU Directive

2011/65/EU.

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% I

DSS 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.

Bias Conditions should also satisfy the following expression: PDISS < (TJ – TC) / RTH J-C and TC = TCASE
