Product Description
The onsemi FOD817SD AC/DC Input Optocoupler is a compact signal isolation device engineered for surface mount applications in industrial and commercial electronic systems. The device incorporates a gallium arsenide infrared emitting diode coupled with a silicon phototransistor, integrated in a 4-pin SMT dual in-line package. This optocoupler is designed to transfer electrical signals between circuits while ensuring galvanic isolation and minimizing signal distortion.
Its AC/DC compatibility makes it suitable for both alternating and direct current input signal isolation, allowing for flexibility in system design. With a maximum forward voltage of 1.4 V and a maximum input current rating of 50 mA, the FOD817SD meets the requirements of a wide variety of analog and digital interface circuits. The current transfer ratio ranges from 50% up to 600%, enabling reliable operation with low or high input signals.
The single channel configuration is ideal for applications where space and isolation requirements are critical. Its 4-pin SMT package type supports automated pick-and-place assembly processes and high circuit density layouts. The optocoupler offers a typical rise time of 4 μs and a fall time of 3 μs, optimizing fast data and signal transfer between isolated circuits. Operational reliability is maintained over a temperature range from -55°C to 110°C, making the product suitable for environments with wide temperature fluctuations.
Safety is assured by compliance with key international standards including IEC, UL, and EN. Tape & reel packaging facilitates efficient integration into surface mount production lines.
Industrial and laboratory users benefit from robust electrical isolation, high-speed switching, and reliable performance for signal transmission, making the FOD817SD an essential component in power electronics, interface modules, and optoelectronic assembly. For engineers and manufacturers seeking optocouplers for PCB layouts, the FOD817SD is a proven choice for overall durability and design flexibility.
