The PLA171 is a single-pole, normally open solid state relay with 800V blocking voltage and 100mA load current capacity, designed for high-isolation switching applications. It features a 6-pin flatpack surface-mount package with 7mm output pin separation and 5000V rms input/output isolation. The relay uses OptoMOS architecture with an infrared LED for control, requiring a maximum 2mA input current and offering a maximum on-resistance of 50Ω. It is UL certified (File E76270) and meets TUV EN 62368-1. The device operates from -40°C to +85°C, has an MSL 1 moisture sensitivity rating, and is ESD sensitive. Its switching characteristics include turn-on and turn-off times of 5ms maximum, with an output capacitance of 11pF at 50V.
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
