The FODM3011R2 NF098 is an optoisolator from the family of Triac, SCR output devices. This line of optoisolators consists of a reliable optocoupler coupled to a power control element, such as a SCR or Triac, and designed to provide isolation and free-wheeling when two circuits, usually AC circuits, must be operated together but must remain electrically isolated. The devices in this family offer features such as high isolation voltage between input and output, wide range of operating temperatures, and a minimum guaranteed turn-on time.

The FODM3011R2 NF098 is a packaged device that contains an infrared LED optically coupled to an output thyristor. The LED light is modulated by applying a control signal to the LED anode. This causes the output SCR or Triac to conduct when the signal is present. The maximum peak repetitive voltage that the FODM3011R2 NF098 can handle is 2.7KV, and its control current is 7mA. It has an operating temperature range of -40°C to +85°C. It is also UL and CSA approved for safety.

The FODM3011R2 NF098 has many practical applications including AC power switching, motor speed control, lamp lighting control, and cyclic timer control. It can also be used for remote control switching, such as garage door openers, light dimmers, motion detectors, and air conditioner fan speed control. It is also used in applications for solid state relays, isolated AC inputs, surge protection, and pulsed transformer circuits.

The working principle of the FODM3011R2 NF098 is as follows. An input signal is applied to the LED anode. This causes the LED to emit light, which is then detected by the output thyristor. When the thyristor is properly triggered, it causes the output SCR or Triac to conduct, establishing a signal path between the two AC circuits. When the signal is removed, the thyristor turns off, and the output SCR or Triac also turns off, thus removing the signal path and isolating the two circuits.

The FODM3011R2 NF098 optoisolator from the Triac, SCR output family is a reliable device that offers isolation and free-wheeling between two AC circuits. It has a wide range of practical applications in various power control and switching applications, and is UL and CSA approved. Its working principle is based on an LED emitting light which is detected by an output thyristor, causing the SCR or Triac to conduct, thus providing a signal path between two circuits.
