The LAA120 is a dual single-pole, normally open solid state relay with optically coupled MOSFET switches, designed for low-power switching applications requiring input-to-output isolation. It is available in an 8-pin DIP package with dimensions of 9.652 ± 0.381 mm in length and 7.620 ± 0.254 mm in width. The relay supports a blocking voltage of 250 V and a continuous load current of 170 mA rms DC, with a maximum on-resistance of 20 Ω. It provides 3750 V rms input-to-output isolation and offers turn-on and turn-off times of up to 5 ms. The device is UL, CSA, and TÜV certified for use in telecommunications, medical equipment, and industrial controls, and meets FCC and VDE compatibility standards. It operates reliably from -40°C to +85°C ambient temperature and is designed for surface mount and through-hole mounting configurations.
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
