The PAA193 is a dual single-pole normally open solid state relay using optically coupled MOSFET technology, designed for low-power switching in instrumentation, data acquisition, and medical equipment applications. It is offered in an 8-pin DIP package with dimensions of 9.652 mm × 7.620 mm, and a surface mount variant is available. The device provides 600 V blocking voltage and 100 mA continuous load current per pole, with a maximum on-resistance of 50 Ω and 5000 Vrms input-to-output isolation. It meets UL E76270 and TUV EN 62368-1 certifications. The relay requires a maximum input current of 5 mA to activate and exhibits turn-on and turn-off times of up to 5 ms. It is classified as MSL 1 for moisture sensitivity and is ESD sensitive, requiring JESD-625 handling.
The OptoMOS® line of solid state relays uses discrete semiconductor components and the patented OptoMOS® architecture to deliver fast, reliable, bounce-free switching in a compact design. From small single-pole, 4-pin relays to multi-pole and multi-function devices, OptoMOS® products are an ideal solid state replacement for larger reed and electromechanical relays. Compared to these old electromagnetic technologies, our OptoMOS® relays offer significantly lower drive current, small package size, no susceptibility to magnetic interaction, and solid state reliability. All of these are key requirements for the design of today's complex, low-power, multi-channel products. The small 4-pin SOP relays combine our state-of-the-art double-molded, vertical-constructio
