The PAA140 is a dual single-pole normally open solid state relay with 400 V blocking voltage and 250 mA load current capacity, designed for high-reliability switching in telecommunications, instrumentation, and medical equipment. It features 3750 V rms input/output isolation, an 8 Ω maximum on-resistance, and is available in 8-pin DIP, SOIC, and surface mount packages. The device has a typical turn-on time of 3 ms and turn-off time of 1 ms, with input control current of 5 mA to activate and 0.4-0.7 mA to deactivate. It is UL recognized, CSA certified, and TÜV EN 62368-1 compliant. The DIP version measures 9.65 mm × 7.62 mm, while the SOIC and surface mount variants have corresponding footprint dimensions. The device meets MSL 1 for surface mount versions and is ESD sensitive.
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
