The PLB171 is a single-pole, normally closed solid state relay with 800V blocking voltage and 80mA RMS load current, designed for applications requiring optically isolated, bounce-free switching. It uses optically coupled MOSFET technology with 5000V input-to-output isolation and has a surface-mount 6-pin flatpack package with dimensions of 7.62mm x 9.65mm. The device has a maximum on-resistance of 55Ω at 80mA load current, requires a maximum input control current of 2mA, and operates over an ambient temperature range of -40°C to +85°C. It is UL recognized and certified to TUV EN 62368-1, with MSL 1 moisture sensitivity and ESD sensitivity 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
