The Vishay Dale 4N28 is a single-channel optocoupler featuring a phototransistor output with a base connection. It provides 5000 VRMS of isolation, making it suitable for applications requiring electrical isolation between circuits. The device operates with a DC input type and has a maximum forward current of 60 mA and a maximum collector current of 100 mA.
This optocoupler is designed for through-hole mounting and comes in a standard 6-DIP package. Its operating temperature range is -55°C to 100°C. Key electrical characteristics include a Vce saturation voltage of 500mV and a minimum current transfer ratio of 10% at 10mA. The input-output coupling capacitance is less than 0.5 pF.
Applications for the 4N28 include AC mains detection, reed relay driving, switch mode power supply feedback, telephone ring detection, logic ground isolation, and logic coupling with high-frequency noise rejection. It interfaces with common logic families and is compliant with RoHS3 directives.
