Datasheets
IXYS announce the immediate availability of the PLA192E and PLA193E, 600V, single-pole, normally open (1-Form-A) Solid State Relays with 150mA and 100mA load current ratings, respectively. These devices use an exclusive patented optically coupled photovoltaic technology and efficient MOSFET output switches to provide an enhanced input-to-output isolation of 5000Vrms.
The 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.

Approvals include: UL Recognized Component: File E76270, CSA Certified Component: Certificate 1175739, EN/IEC 60950-1 Certified Component: TUV Certificate B 12 11 82667 002, DIN EN 60747-5-5 Certified, VDE Certificate.

The PLA192E and PLA193E SSRs are available in production quantities.
