Its 5300Vrms isolation rating means it can withstand transient voltages up to that level between input and output — a common requirement for galvanic isolation in industrial PLC I/O modules, motor drive feedback, and AC mains sensing circuits where safety isolation is mandated by IEC 60950 or UL 1577. The current transfer ratio (CTR) is binned to 160-320% at If=10mA, Vce=5V. This wide min-to-max spread means the design must tolerate a 2:1 variation in output current for a given LED drive — typical for standard-grade optocouplers. The 400mV Vce saturation at 50mA output ensures the transistor pulls close to ground when fully on, leaving headroom for the downstream logic threshold. ## Switching speed and temperature profile Rise and fall times are 2µs typical each; turn-on is 3µs, turn-off 2.3µs. This places the SFH617A-4X016 in the standard-speed optocoupler class — adequate for 10-100 kHz data rates in isolated serial interfaces or PWM feedback, but not for high-speed digital isolation where a logic-output optocoupler would be needed. Operating temperature spans -55°C to +110°C, covering industrial and extended-temperature environments. The 60mA max forward current and 50mA per-channel output give a comfortable margin for typical 5-10mA LED drive in low-power isolated circuits. ## Lifecycle and compliance — active, no end-of-life watch needed Tube packaging is typical for DIP optocouplers — the tubes protect the leads during handling and are compatible with automatic tube feeders on assembly lines.","metaTitle":"Vishay SFH617A-4X016 Optoisolator, 5300Vrms, 160-320% CTR","metaDescription":"Vishay SFH617A-4X016 optocoupler, 5300Vrms isolation, 160-320% CTR at 10mA, 4-DIP through-hole.
