Typical turn-on and turn-off times of 250ns and 260ns respectively mean the part handles data rates up to several MHz, suitable for isolating digital comms lines, PLC digital inputs, or motor-drive feedback paths. 5000Vrms isolation is the reinforced-grade barrier for industrial equipment — it withstands 5 kVAC for one minute between input and output, covering IEC 60950-1 and UL 1577 requirements for safety isolation in motor drives, power supplies, and medical peripherals. Supplied in tubes — the 8-DIP (0.300\", 7.62mm) footprint mates with standard 0.100-inch pitch DIP sockets or wave-solder pads on a two-layer PCB.","metaTitle":"onsemi HCPL2531M Optoisolator, 2-Ch DC, 5000Vrms, 8-DIP","metaDescription":"onsemi HCPL2531M dual-channel transistor-output optocoupler, 5000Vrms isolation, 19-50% CTR at 16mA, 250/260ns switching.
