Optoisolators are a type of semiconductor that uses an optical input to provide electrical isolation between circuits. The 6N137TSR2VM is an optoisolator that is ideal for isolating digital logic signals. This device is also suitable for switching, amplifier protection, and other applications where isolation is desired.

The 6N137TSR2VM is a Schottky optoisolator that uses a LED in a small, surface-mount package. It is available in a range of outputs, including Logic output, and the maximum ratings are 4V and 1A. Its response time is typically 15us at the most (Vcc=5V, RL=1K).

The 6N137TSR2VM Logic Output has two sections: the LED photoemitter, and the Schottky photodiode. The LED section consists of a gallium arsenide LED surrounded by a built-in photodiode for stabilization purposes. The photodiode section is made up of a Schottky diode in a reverse-biased configuration. The device also features an internal buffer amplifier, which is used to boost the signal strength and minimize signal distortion.

Application Field

The 6N137TSR2VM is a popular choice for isolating digital logic signals. Its fast response time and low-voltage operation allow it to be used in a variety of applications, including switching, amplifier protection, motor control, and more. It is also ideal for applications where galvanic isolation is required, such as industrial Ethernet networks and data transmission over long distances.

The 6N137TSR2VM can also be used in medical systems, as the optoisolator helps to protect against electrical interference from external sources. The device can also be used to protect against radio frequency and magnetic interference, which are common in medical and laboratory applications.

Working Principle

The 6N137TSR2VM works by transmitting an electrical signal via light, which is then detected by the photodiode. The signal is then further amplified by the built-in buffer amplifier before being transmitted to the output. The LED section acts to prevent signal degradation and distortion, and the Schottky photodiode helps to ensure accuracy and reliability.

The 6N137TSR2VM is designed to be fairly robust, as it has an operating temperature range of -40 to +85°C. It is also designed to tolerate a wide range of input voltages, from 3.5V to +24V, and is available in a range of lead counts, from 4 to 7, depending on the application.

The 6N137TSR2VM optoisolator is ideal for digital logic signal isolation, and its low-voltage operation, fast response time, and high signal isolation make it a popular choice for a wide range of applications. The device is available in a range of lead counts, and its operating temperature range makes it suitable for both industrial and medical applications.
