Optoisolators like the FODM3011R3V contain both an electro-optically coupled LED and a photovoltaic output. This allows the signal to be isolated, allowing for an effective and streamlined communication. The FODM3011R3V is a Triac, SCR Output optoisolator, which has a variety of uses.

Application Field of FODM3011R3V

The FODM3011R3V optoisolator can be used to perform electrical isolation and signal control in various application fields including HVAC systems, battery powered systems, security systems, home appliance systems, and motor speed control circuits. It is mainly used in low voltage AC/DC application fields where the control of a signal, for instance a Triac, is necessary. The FODM3011R3V is able to effectively switch a Triac on or off when the LED inside is activated with a current. As the optoisolator features a full logic gate, it can be used for high side and low side control.

Working Principle of FODM3011R3V

The FODM3011R3V is an optoisolator which features a photovoltaic output, enabling signals to be isolated without any electrical contact. The unit contains an LED which is optically coupled with the photovoltaic element, or photocoupler. The LED is activated when a voltage signal is applied. This triggers the photovoltaic cell, which in turn activates the output circuit. The output voltage will remain sustained for the duration of the input voltage signal.

The output current of the FODM3011R3V optoisolator is determined by the external resistor. The LED requires a minimum voltage level to be activated, which is around 9V. The maximum voltage and current for the LED is 5V and 20mA respectively. An opto-isolated Triac voltage can range from 4VDC to 400VDC. The on-state resistance is 500 Ohms and the hold-off current is 5mA. All of these parameters need to be within spec in order for the optoisolator to function correctly.

The FODM3011R3V shows good repeatability in various applications and temperature conditions, as well as a significant improvement in the suppression of electromagnetic noise. With its fast on and off switching speeds, the FODM3011R3V has become one of the most popular choices for isolating signals in AC/DC circuit applications.
