Optoisolators, also known as optocouplers, are electronic components used to electrically isolate a circuit or provide galvanic isolation. The 6N136V is a transistor optoisolator that has a photovoltaic output, making it useful for various light-to-voltage or voltage-to-light applications. This article will discuss the 6N136V optoisolator and its application field and working principle.

The 6N136V optoisolator is a solid-state optoisolator consisting of a phototransistor and a photodiode mounted on a plastic molded case. The device is rated at a maximum operating voltage of 15 VDC, and has a typical switching speed of 0.5 microsecond. The package size is compact, measuring 6-pins at only 2.54 mm wide.

The 6N136V optoisolators are mainly used in applications such as communication link isolation, DC-DC converters, current sensing, gate drive isolation, and voltage regulators. By isolating the input signal from the output, the optoisolator ensures reliability in the circuit that is protected from electromagnetic interference.

The 6N136V optoisolator works via a photovoltaic effect using a photo-transistor and a photo-diode. The transistor has an emitter connected to the source of the device and a collector connected to the voltage signal out. The input voltage is applied to the anode of the photo-diode, causing the diode to generate photons in proportion to the input voltage. These photons are then absorbed by the transistor, and the transistor conducts accordingly. This current in the transistor causes the voltage output to be proportional to the voltage input.

The 6N136V optoisolator is a popular device used among designers for its high-speed response time and low power consumption. Its low power consumption and high-isolation voltage make it suitable for industrial, automotive, and medical applications. Furthermore, the 6N136V optoisolator has good photo response and stability, which makes it an ideal choice for light sensing circuits.

In conclusion, the 6N136V optoisolator is a transistor optoisolator with a photovoltaic output, which is widely used in the various applications mentioned above. The optoisolator works by applying a voltage signal to a photo-diode, causing the photons generated to be absorbed by the transistor, which then produces a proportional voltage output. The optoisolator is characterized by its low power consumption, high-speed response time, and high-isolation voltage, making it suitable for a wide variety of applications.
