4N28M Description

Short technical summary and product information.

The 4N28M from ON Semiconductor is a general-purpose optocoupler featuring a gallium arsenide infrared emitting diode driving a silicon phototransistor. This device provides 4170Vrms of isolation and is housed in a standard 6-pin dual-in-line package (DIP) suitable for through-hole mounting.

 

Key electrical characteristics include a nominal forward current of 60 mA and a minimum current transfer ratio (CTR) of 10% at 10 mA. The output transistor has a maximum collector emitter saturation voltage of 500mV and a maximum collector emitter voltage of 30V. The optocoupler operates within a temperature range of -40°C to 100°C.

 

This optocoupler is suitable for applications such as power supply regulators, digital logic inputs, and microprocessor inputs where electrical isolation is required between circuits. The 6-DIP package facilitates easy integration into printed circuit boards using through-hole assembly processes.
