The LBB120 is a dual single-pole, normally closed solid-state relay with 250V blocking voltage and 170mA rms DC load current, designed for telecom switching, instrumentation, and medical equipment isolation. It uses optically coupled MOSFET technology to provide 3750V rms input/output isolation and features a maximum on-resistance of 20Ω, with turn-on and turn-off times of 5ms. Housed in an 8-pin surface mount or flatpack package, it meets UL, CSA, and TÜV EN 62368-1 approvals and is certified for EMI/RFI-free operation. The device supports surface mount tape and reel packaging and is rated for operation from -40°C to +85°C ambient temperature.
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
