The Vishay Dale 4N27 is a standard single-channel optocoupler featuring a gallium arsenide infrared LED and a silicon NPN phototransistor. It provides 5000 VRMS of isolation and is suitable for interfacing with common logic families.
This device operates with a maximum input forward current of 60 mA and a maximum collector current of 100 mA (at t ≤ 1 ms). The collector emitter breakdown voltage is 70 V, and the emitter base breakdown voltage is 7 V. The output exhibits a transistor with base configuration and a Vce saturation voltage of 500mV maximum. The current transfer ratio is a minimum of 10% at 10mA.
The 4N27 is housed in a standard 6-DIP (0.300", 7.62mm) package designed for through-hole mounting. It operates within an ambient temperature range of -55°C to 100°C. Applications include AC mains detection, switch mode power supply feedback, and logic ground isolation.
