Stresses at or above those listed under Absolute Maximum

Ratings may cause permanent damage to the product. 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.

THERMAL RESISTANCE

Thermal performance is directly linked to printed circuit board

(PCB) design and operating environment. Close attention to

PCB thermal design is required.

1 Thermal impedance simulated values are based on a JEDEC 2S2P thermal

test board. See JEDEC JESD-51.

2 θJA was calculated using the total power and maximum junction

temperature.

3 ΨJC was calculated using the package center case temperature.

ESD CAUTION

INSULATION RATINGS

The maximum continuous working voltage refers to the continuous voltage magnitude imposed across the isolation barrier. See the

Insulation Lifetime section for more details.

Table 10. Maximum Continuous Working Voltage

Parameter

Insulation Rating1

Lifetime Conditions

Basic Insulation

AC Voltage

Bipolar Waveform

1129 VPEAK

20 years to 1000 ppm failure at 1129 VPEAK (798 V rms, 50 Hz or 60 Hz sine wave)

Reinforced Insulation

AC Voltage

Bipolar Waveform

1060 VPEAK

20 years to 1 ppm failure at 1060 VPEAK (750 V rms, 50 Hz or 60 Hz sine wave)

1 Insulation capability without regard to creepage limitations. Working voltage may be limited by the PCB creepage when considering rms voltages for components

soldered to a PCB (assumes Material Group I up to 1270 V rms), or package: RI-8-1 package creepage of 8.1 mm, and RW-16 package creepage of 7.8 mm, when

considering rms voltages for Material Group I.
