Littelfuse, Inc. Bidirectional normally open output LCA120

Description
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 n packaging with high performance to give you a reliable product with up to 20% savings in board space compared to other 4-pin SOP products. The dual-pole OptoMOS® relays combine two independent relays into a single 8-pin package, paving the way for designers to condense more functionality into a single component. Low Drive Current High Reliability Optically Isolated Input and Output No EMI or RFI generation Arc-Free with no Snubbing Circuits Machine-insertable and wave-solderable Ac–dc switching Current Limiting (Parts with "L" Suffix) FCC Compatible

Datasheet Summary
Powered by GS/AI

The LCA120 is a single-pole, normally open solid state relay using optically coupled MOSFET technology for 250 V AC/DC switching and 170 mA RMS load current, with 3750 V input-to-output isolation. It is available in a 6-pin DIP package, with surface mount variant LCA120S. The device has a maximum on-resistance of 20 Ω under AC/DC load conditions and requires 5 mA LED current to activate. It operates over an ambient temperature range of -40 °C to +85 °C and meets UL 1577, CSA, and TUV EN 62368-1 safety standards. The relay offers bounce-free switching, no EMI/RFI generation, and is suitable for telecommunications, instrumentation, and medical isolation applications.
