The CPC1125N is a normally-closed, single-pole solid state relay with 400V blocking voltage and 100mA RMS load current capacity, designed to replace electromechanical relays in telecom and instrumentation applications. It uses an optically coupled OptoMOS architecture for 1500V input/output isolation in a 4-pin SOP package measuring 3.81mm x 6.10mm. The relay requires 2mA LED current to operate, has a maximum on-resistance of 35Ω, and supports operating temperatures from -40°C to +85°C. It is UL recognized, CSA certified, and meets TÜV EN 62368-1 standards. The device is moisture-sensitive at MSL level 3 and handles ESD exposure per JESD-625.
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
