The LCB717 is a single-pole, normally closed solid state relay using optically coupled technology for isolation between input and output, designed for low-power switching in sensor circuitry, instrumentation, and medical equipment. It is packaged in a 6-pin DIP with dimensions of 9.144 mm × 7.620 mm × 3.302 mm and features a maximum on-resistance of 0.3 Ω at 1.5 A rms/DC load current and a 30 V blocking voltage. The relay operates with a 2 mA LED drive current and provides 3750 V rms input/output isolation. It is UL recognized (File E76270) and certified to TUV EN 62368-1. The device is not for new designs.
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
