The PLA191 is a single-pole, normally open solid state relay with 400V blocking voltage and 250mA RMS load current capability, designed for telecom switching, instrumentation, and medical isolation applications. It uses an optically coupled MOSFET output with 5000V rms input-to-output isolation and is packaged in a 6-pin DIP. The relay has a maximum on-resistance of 8 Ω under AC/DC configuration, turn-on time of 3 ms, and turn-off time of 1 ms. It is UL recognized, CSA certified, and meets TUV EN 62368-1 standards. The device is rated for operation from -40°C to +85°C ambient temperature and is designated as not for new designs.
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
