The LCA100L is a 350V, 120mA single-pole normally open OptoMOS relay with a maximum on-resistance of 25 Ω, designed for AC/DC switching applications such as telecommunications and medical equipment isolation. It is housed in a 6-pin DIP package with dimensions of 8.382 ± 0.381 mm in length, 7.239 mm in width, and 6.350 ± 0.127 mm in height. The device provides 3750 V rms input/output isolation, features current limiting, and meets UL E76270 and TUV EN 62368-1 certifications. Turn-on and turn-off times are both up to 5 ms, with an off-state leakage current of 1 µA at 350 V. Input control current is ≤5 mA to activate, and the LED forward voltage drop ranges from 0.9 to 1.5 V. The device is rated for an ambient operating temperature of -40 to +85 °C and has an MSL classification of 1 for moisture sensitivity.
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
