Littelfuse, Inc. Bidirectional normally open outputs LAA127L

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
Datasheet Summary
Powered by GS/AI

The LAA127L is a dual single-pole, normally open, current-limiting solid state relay with 250 V AC/DC blocking voltage and 170 mA rms load current capacity, designed for isolation and switching in telecommunications, instrumentation, and industrial control applications. It features 3750 V rms input-to-output isolation, maximum on-resistance of 15 Ω, and uses an optically coupled OptoMOS architecture with an infrared LED for control. The device is housed in an 8-pin DIP package and meets UL, CSA, and EN 62368-1 safety standards. It operates with a control current of up to 5 mA and has a thermal operating range of -40 °C to +85 °C.
