Quality Control: Learn More
onsemi 4N39 is a single-channel optocoupler featuring an SCR output, providing a high isolation voltage of 5300Vrms. This device is designed for applications requiring robust isolation between control and load circuits, particularly in power control systems. The 4N39 exhibits a low LED trigger current (Ift) of 30mA and a static dV/dt rating of 500V/µs, ensuring reliable switching performance. It supports an on-state current (It (RMS)) of up to 300mA and a hold current (Ih) of 1mA. The component is housed in a 6-DIP package for through-hole mounting. Typical forward voltage (Vf) is 1.1V. The 4N39 is suitable for use in industrial control, power supply, and motor drive applications where high voltage isolation and SCR switching characteristics are essential. It operates within a temperature range of -55°C to 100°C.
