The Optoisolator - Transistor, Photovoltaic Output, is an isolator type that gives two signal paths between input and output connections with the aid of an LED and a phototransistor. This isolator type is usually used for applications where electrical isolation and noise immunity are required between two circuits. One of the most popular in this type is the LTV-725VS.

The LTV-725VS is an optically isolated transistor output circuit. It has an low input current of 1 mA and a high output of up to 40 volts. Because of its power output, it is used in applications that require a high voltage signal, such as optical switching and remote control systems. The device works by using an infrared LED to send a beam of light to the phototransistor, which is triggered when the beam is properly detected and absorbed. The phototransistor will then activate or deactivate a circuit, depending on the input signal.

In optical switching applications, the optoisolator can allow two separate circuits to be switched on and off with a single control voltage. An example application is the control of a high-power motor, where the motor can be activated by a low-power signal that is transmitted across an isolation barrier. This is extremely useful when it comes to controlling a high-voltage environment from a low-voltage environment.

The LTV-725VS optoisolator is also used in data isolation systems. One example is when a line of data is sent from one circuit board to another, and the data needs to be securely transmitted without any interference from the other side. The optoisolator will isolate the data by transmitting an LED light signal across the isolation circuit. The light will then activate a transistor, which will in turn trigger a logic signal on the other side of the circuit.

In addition, the device can be used in high-current applications. This is because the device has an internal flyback diode, which helps to protect the phototransistor from damage due to high transient voltages. This makes it an ideal choice for applications that require high power. The LTV-725VS is also capable of handling high-frequency signals, which makes it an ideal choice for applications that require fast data transmission.

Overall, the LTV-725VS optoisolator is an excellent choice for applications that require electrical isolation and noise immunity. It has a wide input voltage range and can handle high-currents, and can even be used in high-frequency applications. This makes it a great choice for applications such as optical switching, remote controls, and data isolation.
