Electrical Characteristics

Unless otherwise specified, these specifications apply over the operating ambient temperature range of 0°C ≤ T_A≤ 70°C. TermPwr = 4.75V.

ISO IMP2119 LOW. Low duty cycle pulse testing techniques are used which maintain

junction and case temperatures equal to the ambient temperature.
