TEST INSTRUMENT: CHROMA 16502 、Zentech1320+Zentech3305

(1). Test Freq : 100KHz , 1V

(2). All test data is referenced to 25℃ ambient.

(3). Operating Temperature Range -55℃ to +125℃.

(4). Rated Current: DC current(A)that will cause an approximate△T of 40℃.

(5). I sat: DC current(A)that will cause Lo to drop approximately 30%.

(6). The part temperature(ambient +temp rise)should not exceed 125℃ 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
