CNY17F43SD [Onsemi]

These optocouplers feature a Gallium Arsenide IRED and an NPN phototransistor in a dual in-line package. They are available in white (M suffix) and black packages, with UL and VDE recognition. Key features include high breakdown voltage (70V minimum for some), closely matched current transfer ratio (CTR) to minimize unit-to-unit variation, and very low coupled capacitance for noise immunity. Suitable for power supply regulators, digital logic inputs, microprocessor inputs, appliance sensor systems, and industrial controls.
