The LCA210 is a dual normally open solid state relay with common input, designed for low-power switching applications such as telecommunications and instrumentation. It features two optically isolated MOSFET outputs with 350 V blocking voltage and 85 mA continuous load current, controlled by a single input signal. The device offers 3750 V rms input/output isolation and uses OptoMOS architecture for reliable, EMI-free operation. It is packaged in an 8-pin DIP with dimensions of 9.652 mm x 7.620 mm and is certified as UL recognized, TUV EN 62368-1 compliant, and VDE compatible. On-resistance is specified at a maximum of 35 Ω, with turn-on and turn-off times of 3 ms maximum. The part is not recommended 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
