Optoisolators - Transistor, Photovoltaic Output, such as PS2761-1-V-F3-K-A, are utilized for electrical isolation in a wide variety of applications by using a light-emitting diode (LED) to optically drive a phototransistor output.

The basic operating principle is based on a pair of gallium arsenide (GaAs) LEDs. The LEDs are optically coupled within a single package, with one LED used for the light source and the other LED used for the light detector. The light output from the source LED is received by the detector, which in turn produces an electrical signal. The electrical signal is then transmitted through the phototransistor layer to an attached electrical circuit, providing complete electrical isolation.

The common applications for this type of optoisolator include automobile electrical systems, security systems, aerospace and defense systems, industrial process control systems, medical instrumentation, and consumer electronics. The optoisolator can be used to provide electrical isolation for devices or to protect the device from over-voltage or over-current damage.

The PS2761-1-V-F3-K-A optoisolator is a NPN phototransistor output with an operating wavelength of 655nm (red). The forward voltage of the source LED is 2V typical, and the average occupancy current is 6mA. The reverse voltage of the detector LED is one volt given a reverse current of 1.5mA. The reverse current of the phototransistor is 40uA at 25oc.

The collector current of the phototransistor is 20mA maximum, and the collector-sustaining voltage is 50V maximum. The pulse width modulation frequency of the phototransistor is 100KHz maximum. With a collector-emitter saturation voltage of 0.2V maximum at 10mA collector current, the PS2761-1-V-F3-K-A optoisolator provides a wide operating temperature range from -40oc to 125oc.

The PS2761-1-V-F3-K-A optoisolator is also capable of providing electrical noise immunity, transient protection, and signal integrity in systems with high noise environments. The LED source within the optoisolator is designed to ensure that the system will respond to input signals while ignoring electrical noise. The phototransistor is designed to provide transient protection, allowing the system to continue to function properly in noisy or extreme conditions.

The PS2761-1-V-F3-K-A optoisolator is ideal for use in applications where electrical isolation is required. The phototransistor output provides excellent signal accuracy and noise immunity, making it suitable for use in a range of applications. The optoisolator also offers wide temperature range, allowing for operation in extreme temperatures. With these features, the PS2761-1-V-F3-K-A optoisolator can be confidently used in a number of applications to ensure reliable operation while providing the necessary electrical isolation.
