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.
