This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Table 8. Maximum Continuous Working Voltage1 Parameter Max Unit Reference Standard2 AC Voltage Bipolar Waveform Basic Insulation 849 V peak 50-year minimum insulation lifetime Reinforced Insulation 768 V peak Lifetime limited by package creepage maximum approved working voltage per IEC 60950-1 Unipolar Waveform Basic Insulation 1698 V peak 50-year minimum insulation lifetime Reinforced Insulation 885 V peak Lifetime limited by package creepage maximum approved working voltage per IEC 60950-1 DC Voltage Basic Insulation 1092 V peak Lifetime limited by package creepage maximum approved working voltage per IEC 60950-1 Reinforced Insulation 543 V peak Lifetime limited by package creepage maximum approved working voltage per IEC 60950-1 1 The maximum continuous working voltage refers to the continuous voltage magnitude imposed across the isolation barrier. See the Insulation Wear Out section for more details. 2 Insulation lifetime for the specified test condition is greater than 50 years. THERMAL RESISTANCE Thermal performance is directly linked to PCB design and operating environment. Careful attention to PCB thermal design is required. θJA is the natural convection junction to ambient thermal resistance measured in a one cubic foot sealed enclosure. θJC is the junction to case thermal resistance. Table 9. Thermal Resistance Package Type θ JA 1 θ JC 1 Unit RW-16 59.7 28.3 °C/W 1 Thermal impedance simulated values are based on a JEDEC 2S2P thermal test board with no vias. See JEDEC JESD51.
