4N48 Description

Short technical summary and product information.

The 4N48 optoisolator from TT Electronics (Optek Technology) provides robust 1kV electrical isolation, making it suitable for applications requiring separation between input and output circuits. Encased in a TO-78 hermetically sealed package, this component is designed for high-reliability use.

 

Key electrical characteristics include a minimum current transfer ratio (CTR) of 100% at 1mA, a maximum CTR of 5, and a maximum collector-emitter voltage (VCE) of 40V. The device operates with a typical forward current (IF) of 40mA and has a wavelength of 935nm. It also features relatively fast rise and fall times, both at a maximum of 20µs.

 

The 4N48 is specified for operation across a wide temperature range of -55°C to 125°C. Its hermetically sealed TO-78 package and high isolation voltage make it well-suited for use in electrically noisy or dirty environments, as well as in industrial equipment, medical equipment, and office equipment where reliable isolation is critical.
