Absolute maximum ratings are limiting values above which SST4117 serviceability may be impaired. 2. Due to symmetrical geometry, these units may be operated with source and drain leads interchanged 3. This parameter is measured during a 2ms interval 100ms after power is applied. (Not a JEDEC condition.)
