The LAA125L is a dual normally open (1-Form-A) solid state relay with current limiting, featuring two optically coupled MOSFET switches in an 8-pin DIP package. It supports a maximum load voltage of 350 V AC/DC and a continuous load current of 150 mA rms. The relay offers 3750 V rms input/output isolation, a maximum on-resistance of 18 Ω, and turn-on and turn-off times of up to 5 ms. It is UL recognized and CSA certified, with TUV EN 62368-1 compliance. The device operates within an ambient temperature range of -40 to +85 °C and is designed for applications requiring low drive power, no EMI/RFI generation, and compact board space utilization.
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
