Working Principle of 4N46-060E

The 4N46-060E Transistor, Photovoltaic Output optoisolator is a diode-driven optoisolator consisting of a photodiode and a six-terminal NPN transistor. The optoisolator works by converting an electrical input into a proportional, isolated signal output. When an input current (up to 15mA) is applied to the anode of the photodiode, light energy is created, and this light is detected by the photodiode’s phototransistor. The resulting current is then amplified by the transistor, supplying the output current. In this way, the output current is proportional to the applied input current, creating a highly accurate signal transmission.

In addition to providing highly accurate signal transmission, the 4N46-060E optoisolator also provides electrical isolation. The optoisolator has an isolation voltage rating of 5000 Volt RMS, meaning that it can completely isolate two circuits with potentials up to 5000 volts. This provides highly reliable electrical insulation, which is essential for a wide range of applications.
