Note: The Si85xx is suitable for basic and reinforced electrical isolation only within the safety limit data. Maintenance of the
safety data is ensured by protective circuits. The Si85xx provides a climate classification of 40/125/21. Note that the
Si85xx is compliant with the IEC60747-5-2 but neither certified nor inspected to IEC60747-5-2. The Si85xx is
compliant, certified, and factory-inspected to IEC60950.

Notes:
1. Maximum value allowed in the event of a failure. Refer to the thermal derating curve in Figure 1.
2. The Si85xx is tested with V DD = 5.5 V, T J = 150 oC, C L = 15 pF, and with an input current from IIN to IOUT equal to
20 Amps at 500 kHz (duty cycle = 50%).
