The FOD852 is a photodarlington optocoupler that provides 5000V of electrical isolation between the input and the output. Using a Gallium Arsenide IR emitting diode as the source driving a silicon output in Darlington configuration with an integral base-emitter resistor. The device is enclosed in a DIL-4 package and is suitable for a number of applications such as: power supply regulators, digital logic inputs and microprocessor inputs. * Provides electrically isolated protection for devices * Suitable for Pb-free IR reflow soldering * Compact 4-pin through-hole package * High current transfer ratio, 1000% min. * High input-output isolation voltage 5000V AC rms * High operating temperature 100°C * UL, C-UL and VDE approved https://elecena.pl/product/27240007/fairchild-semiconductor-fod852-darlington-optocoupler 2024-11-12 https://elecena.pl/product/27240007/fairchild-semiconductor-fod852-darlington-optocoupler 2025-03-24 https://elecena.pl/product/27240007/fairchild-semiconductor-fod852-darlington-optocoupler 2025-05-07 https://elecena.pl/product/27240007/fairchild-semiconductor-fod852-darlington-optocoupler 2025-06-12 https://elecena.pl/product/27240007/fairchild-semiconductor-fod852-darlington-optocoupler 2025-07-21 https://elecena.pl/product/27240007/fairchild-semiconductor-fod852-darlington-optocoupler 2025-09-20 https://elecena.pl/product/27240007/fairchild-semiconductor-fod852-darlington-optocoupler 2026-04-13 https://elecena.pl/product/27240007/fairchild-semiconductor-fod852-darlington-optocoupler 2026-05-06 https://elecena.pl/product/27240007/fairchild-semiconductor-fod852-darlington-optocoupler 2026-07-13 https://elecena.pl/product/27240007/fairchild-semiconductor-fod852-darlington-optocoupler 2026-08-05
