The LCA127L is a 250V, 170mA rms, single-pole normally open solid state relay using OptoMOS technology for optical isolation and low on-resistance switching. It is packaged in a 6-pin DIP with dimensions of 8.382mm × 6.350mm × 3.302mm, suitable for surface mount or through-hole mounting. It features 3750V rms input-to-output isolation, on-resistance of up to 15Ω at 170mA, and switching times of up to 5ms. The device meets UL E76270, CSA 1175739, and TÜV EN 62368-1 standards, and is rated for ambient temperatures from -40°C to +85°C.
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
