The LCA129 is a 250V, 170mA rms, single-pole, normally open solid state relay with optically coupled MOSFET output, designed for low drive current applications and direct replacement of electromechanical relays. It is available in a 6-pin DIP package with dimensions of 8.382±0.381mm length, 7.620±0.127mm width, and 3.302±0.051mm height. The device provides 3750V rms input-to-output isolation, an on-resistance of up to 20Ω at 170mA, and a 2mA maximum control current. It meets UL, CSA, and EN 62368-1 safety standards and is rated for operation from -40°C to +85°C ambient temperature. The part supports both AC/DC load configurations and features no EMI/RFI generation.
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
