It delivers a current transfer ratio of 250% to 500% at 1 mA forward current, making it suitable for applications where the LED drive current is limited and a high CTR margin is needed to guarantee the output saturates over temperature and lifetime. The transistor output can sink up to 50 mA and withstand 55 V on the collector, which covers driving a logic input, a small relay, or a low-side switch in isolated power-supply feedback loops, motor-drive status signals, and industrial PLC I/O modules. ## CTR spread and bias design The 250% minimum CTR at 1 mA forward current is the number to design around. The wide CTR range (250% to 500%) means the load resistor on the output side must be chosen so that even at the minimum CTR the output transistor saturates — the 400 mV Vce(sat) maximum gives a clean logic low. At the maximum CTR, the same resistor will still be within the output current rating of 50 mA, so no overdrive concern. ## Switching speed and timing budget Rise and fall times are 3.5 µs and 5 µs typical, with turn-on and turn-off times of 6 µs and 5.5 µs. That places the usable data rate around 50 kbps or slower — fine for 50/60 Hz zero-crossing detection, relay-coil feedback, or slow GPIO isolation, but not for high-speed digital buses like SPI or I²C. The DC input type means the LED is simply on or off; no AC coupling or carrier modulation is needed. ## Temperature range and environment The ROHS3 compliance simplifies EU and global compliance paperwork. ## Lifecycle and sourcing That means no last-time-buy pressure and no forced redesign for a replacement. For dual-sourcing resilience, Vishay's SFH6186 family includes multiple CTR bin options (the '-5' bin is this one); a pin-compatible sibling with a different CTR bin may be qualified in parallel if the design can tolerate the CTR spread.","metaTitle":"SFH6186-5X001T Optocoupler, 5300Vrms, 250-500% CTR, 4-SMD","metaDescription":"SFH6186-5X001T Vishay optocoupler: 5300Vrms isolation, 250-500% CTR at 1mA, transistor output, -55°C to 100°C, 4-SMD gull wing.

The forward voltage is 1.1 V typical, so a 3.3 V logic output can drive the LED through a series resistor sized for 1 mA to 5 mA. The transistor output saturates at 400 mV maximum, which is a valid logic low for a 3.3 V receiver.
