The LBB110 is a dual normally closed (1-Form-B) solid state relay with two independently controlled optically coupled MOSFET switches in an 8-pin DIP package, designed for low-power switching applications such as telecommunications and medical equipment isolation. It supports a blocking voltage of 350 V and a continuous load current of 120 mA rms DC, with a maximum on-resistance of 35 Ω. The device provides 3750 V rms input-to-output isolation and is certified by UL, CSA, and TUV for EN 62368-1. It features no EMI/RFI generation, low drive power requirements, and surface mount and tape & reel options are available for different packaging needs.
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
