Categories: Triac, SCR Output Optoisolators
Quality Control: Learn More
The onsemi 4N40 is a single-channel optocoupler featuring an SCR output. This component provides 5300Vrms of isolation and is housed in a 6-DIP package suitable for through-hole mounting. It offers a 400V off-state voltage and a 300mA RMS on-state current. The LED trigger current (Ift) is specified at a maximum of 14mA, with a typical forward voltage (Vf) of 1.1V. The device also exhibits a static dV/dt of at least 500V/µs and a hold current (Ih) of 1mA. The 4N40 is designed for applications requiring high voltage isolation and solid-state switching, commonly found in power control systems and industrial automation. Its operating temperature range is -55°C to 100°C.
