Quality Control: Learn More
The onsemi 4N31S is a single-channel optoisolator featuring a Darlington output with base control. This device provides 5300Vrms isolation and is housed in a 6-SMD gull wing package, suitable for surface mounting. The input accepts DC signals with a typical forward voltage of 1.2V at 80mA maximum forward current. The output stage is a Darlington transistor capable of handling up to 30V and 150mA per channel, with a maximum Vce saturation of 1.2V. A minimum current transfer ratio of 50% at 10mA is specified. The 4N31S operates across a temperature range of -55°C to 100°C and features typical turn-on and turn-off times of 5µs and 40µs respectively. This component finds application in industrial automation, telecommunications, and power supply control systems.
