TEST INSTRUMENT: CHROMA 16502 、Zentech1320+Zentech3305
(1). Test Freq : 100KHz , 0.5V
(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
