Optoisolators are devices that employ optical techniques to enable signals to pass between different and isolated circuits. These devices are used in many industrial, commercial, and consumer applications to provide isolating protection against hazardous voltages and electrical noise that are generated by other parts or sections of the circuit. One type of opto-isolator is the H11AV1SR2M. It is a transistor, photovoltaic output opto-isolator and can be used for a variety of applications.

The H11AV1SR2M consists of two separate sections: the photovoltaic section and the transistor section. The photovoltaic section contains a gallium arsenide (GaAs) infrared light emitting diode (LED) and an integrated photodiode. When the LED is activated, it emits infrared light through a lens that is directed towards the photodiode. As the electrons flow through the photodiode, they create a voltage potential that is relayed to the transistor section.

The transistor section contains a Darlington pair, which is an arrangement of two bipolar transistors that amplifies a signal while keeping the voltage gain the same as the input. This allows for a secure isolation between the photovoltaic and transistor sections, making sure that there is no leakage of current or voltage. The Darlington pair is connected to a resistor that is used to set the peak current of the output stage and to protect the output stage from damage due to over-voltage.

The H11AV1SR2M opto-isolator is used in a variety of applications. One of its main applications is to protect sensitive components on a circuit board from the high voltage and noise generated by other sections of the board. It can also be used to isolate signals across RS232, USB, and digital I/O lines, as well as on power circuits, such as motor drives. It can also be used in motor controllers, motor monitoring and protection circuits, and switching power supplies.

As the H11AV1SR2M opto-isolator is a transistor, photovoltaic output device, it functions by the output stage switching from a high state to a low state when the input signal is present. When the input signal is absent, the output stage is returned to its high state. As the LED is activated, it emits infrared light that is directed towards the photodiode. The photodiode then creates a voltage potential that is relayed to the transistor section. The output signal is produced when the Darlington pair amplifies the signal, thus providing isolation between the photovoltaic and transistor section.

The H11AV1SR2M opto-isolator is a transistor, photovoltaic output device that is used in many different applications to protect sensitive components on a circuit board from high voltage and noise, such as across RS232, USB, and digital I/O lines and motor drives. It functions by the output stage switching from a high state to a low state when the input signal is present, and by amplifying the signal using a Darlington pair in order to provide secure isolation between the photovoltaic and transistor section.
