Its 5300 Vrms isolation rating makes it a candidate for galvanic isolation in industrial controls, motor drives, and power supplies where you need to separate high-voltage and low-voltage domains. The current transfer ratio (CTR) is specified between 160% and 320% at a 10 mA forward current — a wide enough band that you should check the minimum at your actual drive current to guarantee the logic threshold at the output side. ## Output stage and switching speed The output is a phototransistor with the base brought out, which gives you the option to bias the base for faster switching or to use the transistor in a common-base configuration. Typical turn-on time is 3.2 µs and turn-off is 3 µs, with rise and fall times of 2 µs and 2.5 µs respectively. That puts it in the general-purpose speed class — fine for 50/60 Hz line sync, relay drivers, or status feedback, but not for high-speed data links. The 6-DIP package (0.300-inch body width) is a standard through-hole footprint — easy to hand-assemble or wave-solder, and the 7.62 mm pin pitch matches common proto-board layouts. No LTB window to track.","metaTitle":"SFH600-3 Optocoupler, 5300Vrms Isolation, 160-320% CTR","metaDescription":"SFH600-3 optocoupler with 5300Vrms isolation, transistor with base output, 160-320% CTR at 10mA.
