Optoisolators are components that use light emissions to provide electrical isolation between two parts of a circuit. Transistor, Photovoltaic Output optoisolators use an electrically isolated light emitting diode (LED) as the input stage and a photoconductive transistor as the output stage. The 6N138#300 is an example of this type of optoisolator.

The 6N138#300 optoisolator has a current transfer ratio of 10:1, meaning that the collector current of the output stage is 10% of the input current on the LED. The transfer ratio can vary from part to part and is even temperature dependent, so it should always be verified in the datasheet of a particular optoisolator before use. The input voltage of the LED ranges from 1.3 Volts to a maximum of 5 Volts. The output transistor can handle a maximum of 30 Volts and has a maximum collector current of 0.5 Amps.

The 6N138#300 optoisolator is typically used in applications where electrical isolation must be maintained. Such applications include motor controllers, power supplies and other circuits that require the signal on one side to be isolated from the other. The optoisolator prevents any interference from one part of the circuit to the other, protecting against voltage spikes, ground loops and other forms of interference. Optoisolators are also used in communication applications such as RS232, where an LED can be used to transmit data.

The operation of the 6N138#300 is based on the principle of optical isolation. The LED is illuminated when a small current passes through it. This in turn causes the photoconductor in the output transistor to conduct, allowing current to flow from the collector to the emitter of the transistor. Since the only communication between the LED and the output transistor is the light emitted by the LED, no electrical connection needs to be made between the two sides of the circuit, thus providing the desired isolation.

The 6N138#300 is usually housed in a hermetically sealed DIP package, making it well protected from the environment. The optoisolator has excellent reliability and a minimum life of 50,000 hours thanks to its protective construction. The lifetime of the optoisolator varies depending on the temperature, current and input voltage, which should always be taken into account when designing with this component.

In conclusion, the 6N138#300 optoisolator is a reliable and convenient isolation component for applications where electrical isolation is required. It offers a wide range of input voltages and currents, and a maximum collector current of up to 0.5 Amps. Thanks to its hermetic package, it is well protected from the environment and offers excellent reliability and long-term durability.
