5300Vrms isolation in a 4-SMD Gull Wing package
The Vishay SFH617A-1X007T is a single-channel optocoupler with a phototransistor output, rated for 5300Vrms isolation between input and output. It comes in a 4-SMD Gull Wing package, surface-mount compatible, and is specified over a -55°C to 110°C operating range. The DC input drives an infrared LED (typical forward voltage 1.35V) coupled to a phototransistor that can switch up to 70V at 50mA per channel. This part is suited for isolating digital or slow analog signals in power supplies, motor drives, PLC I/O modules, and industrial sensor interfaces where galvanic isolation is required.
The current transfer ratio (CTR) is specified at 40% minimum and 80% maximum, both measured at 10mA forward current. Typical turn-on time is 3µs and turn-off time 2.3µs, with rise and fall times both 2µs.
