The PLA194 is a single-pole, normally open solid state relay with a 600 V blocking voltage and 130 mA rms load current capacity, designed for optically isolated switching in sensor, instrumentation, and medical equipment applications. It uses OptoMOS architecture with a 5000 V rms input/output isolation barrier and comes in a 6-pin DIP package. The relay has a maximum on-resistance of 35 Ω, turn-on and turn-off times of 3 ms and 2 ms respectively, and operates over an ambient temperature range of -40°C to 85°C. It is UL recognized and meets TUV EN 62368-1 standards. The device is 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
