PLA192E and PLA193E devices meet partial discharge testing and are certified to the EN 60747-5-5 standard which guarantees that the devices will not fail under extended periods of time and voltage bias. Partial discharge testing is a production isolation-material quality test. Unlike most isolation safety standards, such as UL1577 and EN60950, which rely on gross over-voltage testing to ensure isolation robustness, partial discharge testing correlates specifically to long term stability of the isolating material that maintains its isolating properties even after prolonged voltage bias.
EN 60747-5-5 is a new optocoupler safety standard and requires 100% partial discharge testing of optocouplers. Partial discharge testing measures a very low leakage current that develops as a result of the isolation material breakdown. The PLA192E and PLA193E have a continuous isolation barrier working voltage of 1000V and the partial discharge test is an additional isolation test that is performed after the gross high voltage isolation test.
Applications include DC to AC power conversion (solar, wind, renewable energy sources), high voltage battery power supplies, designs requiring high continuous DC voltage and other designs (currently primarily European) that require optocoupler partial discharge testing.
