The PLB190 is a single-pole, normally closed solid state relay using OptoMOS architecture for optically isolated AC/DC switching, with a maximum blocking voltage of 400 V and a continuous load current of 130 mA rms. It features a 6-pin DIP package, 25 Ω maximum on-resistance in AC/DC configuration, and 5000 V rms input/output isolation. The device meets UL E76270, VDE, FCC, and TÜV EN 62368-1 certifications, with an operating temperature range of -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
