The LCA220 is a dual single-pole normally open solid state relay with common input, designed for telecommunications and instrumentation applications. It features two optically coupled MOSFET switches controlled by a single input signal, providing 3750 Vrms input-to-output isolation. The device is packaged in an 8-pin DIP and has a maximum load current of 120 mA rms DC, a blocking voltage of 250 V, and a maximum on-resistance of 20 Ω. It meets UL Recognized Component File #E76270 and TUV EN 62368-1 standards, with no EMI/RFI generation. The relay supports surface mount and through-hole mounting variants, with a typical turn-on and turn-off time of 5 ms.
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
