The LBA127L is a dual solid state relay in an 8-pin DIP package, integrating one current-limited normally open (1-Form-A) and one normally closed (1-Form-B) relay using optically coupled MOSFET technology. It provides 3750 Vrms input-to-output isolation, supports a maximum blocking voltage of 250 V, and handles a continuous load current of 150 mA rms for the Form-A output and up to 400 mA peak for the Form-B output. The on-resistance is specified up to 15 Ω, with turn-on and turn-off times of 5 ms maximum. It is rated for operation from -40°C to +85°C and is UL, CSA, and TÜV certified. The device is RoHS compliant and designed for telecommunications, instrumentation, and medical applications requiring isolated switching.
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
