Characteristics
- All test data is based on 25 ambient.
- DC current (A) that will cause an approximate T 40.
- DC current (A) that will cause L0 to drop approximately 30% Typ.
- Operating temperature range: -55 to +125.
- The part temperature (ambient + temp rise) should not exceed 125 under worst-case operating conditions. Circuit design, component, PWB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.
