6. Operating temperature: -40 to +125 The part temperature (ambient temperature +
temperature rise) should not exceed the upper limit of the operating temperature under worst
case operating conditions. Circuit design, component placement, PWB trace size and
thickness, airflow and other cooling provisions all affect the part temperature. Part temperature
should be verified in the end application.
7. The Volt-time product is 34.2 V-usec typical.
