Dimensions (unit:inch/ mm):

Recommended Layout: [unit: inch/ mm]

Note：

·All test date is referenced to 25℃ ambient.

·DC current(ldc) that will cause an approximate △T of 40℃.

·DC current(last) that will cause Lo to drop approximately 20%.

·Operating temperature range:-40

℃ to +125℃.

• The part temperature (ambient + temp rise) should not exceed125℃ under the worst 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.
