The LBA127 is a dual single-pole solid state relay with one normally open (1-Form-A) and one normally closed (1-Form-B) channel, designed for AC and DC switching applications. It is housed in an 8-pin DIP package with dimensions of 9.652 ± 0.381 mm in length and 7.620 ± 0.254 mm in width. Each channel supports a maximum blocking voltage of 250 V and a continuous load current of 200 mA RMS DC, with an on-resistance of up to 10 Ω. The device offers 3750 V RMS input/output isolation, low drive power requirements, and no EMI/RFI generation. It is UL recognized, CSA certified, and compliant with TUV EN 62368-1. The operational ambient temperature range is -40 to +85 °C, and it meets MSL 1 moisture sensitivity for the DIP variant.
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
