Quality Control: Learn More
The onsemi 4N28S is a single-channel optoisolator featuring a transistor output with base connection. This component provides 5300Vrms of isolation, making it suitable for applications requiring robust electrical separation. It is packaged in a 6-SMD, Gull Wing configuration for surface mounting and operates across a temperature range of -55°C to 100°C. The device exhibits a typical forward voltage of 1.18V and a minimum current transfer ratio of 10% at 10mA, with a maximum DC forward current of 100mA. The output transistor has a saturation voltage of 500mV (max) and supports an output voltage of up to 30V. Typical turn-on and turn-off times are 2µs. This optoisolator finds utility in industrial control, power supplies, and telecommunications equipment where signal isolation is critical.
