5300 Vrms isolation in a 4-SMD gull-wing package
The SFH6156-1 is a single-channel phototransistor optocoupler from Vishay, rated for 5300 Vrms isolation. That isolation voltage provides a galvanic barrier between a DC input and a transistor output, suitable for breaking ground loops in industrial controls, motor drives, and medical power supplies where safety isolation is required. The 4-SMD gull-wing package sits flat on the board for automated pick-and-place.
Current transfer ratio spans 40% min to 80% max at If=10 mA. Typical turn-on time is 3 µs, turn-off 2.3 µs, with rise and fall both 2 µs. These switching speeds suit 10–100 kHz PWM signals or digital isolation at moderate data rates; for faster edges, a logic-output optocoupler would be a better fit.
Active production, ROHS3 compliant, tube delivery
Vishay lists the SFH6156-1 as Active and ROHS3 compliant. For reel or tape-and-reel quantities, confirm the specific Vishay reel suffix with your order.
The temperature grade spans –55°C to 100°C, covering outdoor telecom cabinets, factory-floor enclosures, and under-hood automotive auxiliary circuits. Maximum output voltage is 70 V, output current 50 mA per channel, and forward current 60 mA. These ratings define the load side: a 24 V PLC input or a 48 V telecom signal is within range; a 120 VAC relay coil would need a higher-voltage optocoupler.
