That isolation level supports reinforced insulation in mains-connected power supplies, motor drives, and industrial PLC I/O modules where safety isolation is required. The current transfer ratio is specified as a minimum of 160% and a maximum of 320% at a forward current of 10 mA — a tight bin that gives the designer a predictable LED drive current and logic-level output swing across the full -55°C to 100°C operating range. ## Switching speed and output drive Typical rise and fall times are 2 µs each, with turn-on time of 3 µs and turn-off time of 2.3 µs. This places the SFH6106-4 in the general-purpose speed class — adequate for 50/60 Hz line synchronization, relay drivers, and digital input sampling at low kHz rates, but not for high-speed serial isolation. The transistor output can sink up to 50 mA and block up to 70 V, with a Vce saturation maximum of 400 mV at the rated current, keeping power dissipation low in the on-state. ## Package and mounting for production Housed in a 4-SMD Gull Wing package (supplier device package 4-SMD), this part is designed for surface-mount assembly. The Gull Wing leads provide good coplanarity for automated pick-and-place and visual solder-joint inspection. The Tube shipping medium means the parts arrive in a rigid anti-static tube — verify your feeder setup accepts Tube-fed components or plan a transfer to tape-and-reel if your line is reel-only. ## Lifecycle and compliance The wide temperature range and isolation rating make it a stable choice for industrial and automotive-grade BOMs.","metaTitle":"SFH6106-4 Optocoupler, 5300Vrms, 160-320% CTR","metaDescription":"SFH6106-4 Vishay optocoupler: 5300Vrms isolation, 160-320% CTR at 10mA, transistor output, -55°C to 100°C, 4-SMD Gull Wing.
