It is designed for signal isolation in industrial controls, PLC modules, motor drives, and power-supply feedback paths where multiple isolated channels share a common package. ## CTR range and switching — what matters for the BOM The current transfer ratio spans 50% to 300% at a forward current of 5mA. A 50% minimum CTR means the output transistor can sink at least 2.5mA with 5mA input — enough to drive a TTL or CMOS logic input directly, but check the load current against the 50mA per-channel maximum. The 300% upper bound means the part can saturate with very little LED drive, but the turn-on and turn-off times (5µs and 4µs typical, with 4µs rise and 3µs fall) set the practical switching speed below 100 kHz. For higher data rates, look at a logic-output optocoupler instead. ## Output voltage and saturation — rail compatibility The output transistor is rated for 70V collector-emitter voltage, so it can switch 5V, 12V, 24V, or even 48V logic rails. The 400mV maximum Vce saturation at the rated current keeps the voltage drop low enough for most logic thresholds. With a 50mA per-channel output current, each channel can drive a small relay, an LED indicator, or a logic input directly. ## Package and rework — 16-SOIC in a tube The SFH6916 comes in a 16-SOIC package (0.173\" body width, 4.40mm) with a 1.27mm pitch — standard for hand-assembly and rework. The tube shipment keeps the leads straight; no baking required if the moisture-barrier bag is intact.","metaTitle":"SFH6916 Optocoupler, 4-Ch Transistor Output","metaDescription":"SFH6916 quad transistor optocoupler, 3750Vrms isolation, 50-300% CTR at 5mA, 70V output, -55°C to 100°C.

Pin-compatible alternatives exist within the same package family, but the CTR range, isolation voltage, and switching speed differ — verify the specific ratings against your design before substituting."},{"question":"Is SFH6916 compatible with 5V microcontroller output?","answer":"Yes. With a typical forward voltage of 1.15V and a 5mA forward current, a 5V microcontroller GPIO can drive the LED directly through a current-limiting resistor.
