Its 5300 Vrms isolation rating covers reinforced isolation for industrial drives, medical equipment, and power-supply feedback loops where galvanic separation between primary and secondary is non-negotiable. The 8-SMD gull-wing package suits surface-mount assembly without through-hole compromises. Minimum current transfer ratio of 19% at 16 mA forward current means the output transistor can sink at least 3 mA with 16 mA LED drive. That is enough to pull a logic input low through a 10 kΩ pull-up to 5 V, but leaves little headroom if you need to drive a heavier load or a long cable. The 400 mV Vce(sat) max ensures the output rail stays clean when saturated. For designs that need more gain, look for a higher-CTR variant in the same family. ## 300 ns switching — not for high-speed, fine for 1 Mbps class Typical turn-on and turn-off times of 300 ns each give a combined propagation delay around 600 ns. That supports data rates up to about 1 Mbps — adequate for isolated SPI clock, fault flags, or PWM at tens of kHz. If you need 10 Mbps or faster, a digital isolator or high-speed optocoupler is the right choice. ## -55°C to 100°C — industrial and cold-environment ready The 100°C upper limit is below the 125°C military-grade boundary, but the -55°C low end handles cold starts in northern climates without issue. ## Lifecycle and compliance ROHS3 compliant, so it fits current European and global RoHS requirements without exemption paperwork.","metaTitle":"SFH6345-X017T Optocoupler, 5300 Vrms, Transistor Output","metaDescription":"SFH6345-X017T optocoupler: 5300 Vrms isolation, transistor output, 19% min CTR at 16 mA, 300 ns switching, -55°C to 100°C.
