PLA192/PLA193 Solid State Relays IXYS Integrated Circuits PLA192E/PLA193E Solid State Relays are 600V, single-pole, normally open SSRs with 150mA and 100mA load current ratings, respectively. With an exclusive patented optically coupled photovoltaic technology and efficient MOSFET output switches, the devices provide an enhanced input-to-output isolation of 5000 Vrms. Partial discharge testing and EN60747-5-5 certification ensure the IXYS Integrated Circuits PLA192E/PLA193E Solid State Relays will not fail after extended time and voltage bias.
