6N138WV

Opto-isolators, also known as opto-couplers, electro-optic couplers, or optical isolators, are devices used to isolate one electrical circuit electrically and optically. They are primarily used in digital electronics applications where high noise rejection, circuit protection, and/or isolation are desired. A 6N138WV opto-isolator is an opto-isolator of the transistor photovoltaic-output type. It is designed for use in a wide range of applications involving a variety of voltages, currents, and signal types.

The 6N138WV opto-isolator has a wide range of applications, as any opto-isolator would. It is often used for control applications, data transmission, computer logic systems and electrically isolated circuits. In the transmission of signal in the presence of high electrical noise, the 6N138WV opto-isolator provides an effective barrier against noise, ensuring signal integrity. In addition, it can help protect circuits from voltage changes and other overload effects.

In terms of its working principle, the 6N138WV opto-isolator consists of two different parts. The first part is an LED (light emitting diode) which is usually powered by voltage and current in the range of 5-100 volts and 10-50 mA respectively. The second part is a photodetector, usually a phototransistor or a photodarlington, which senses the generated light and thus produces a corresponding electrical signal. The purpose of the LED is to generate light when current passes through it, and the photodetector then absorbs this light and produces a corresponding electrical signal.

The 6N138WV opto-isolator can be used in a variety of applications. For example, it can be used for isolating two circuits, isolating a single circuit from a ground, or for driving a load which requires more current than the driving circuit can provide. It is also used in medical equipment, security systems, industrial equipment, and automotive systems.

Opto-isolators provide a convenient way to transmit signal between different circuit elements without allowing any physical connection, and the 6N138WV opto-isolator is designed to provide this in a versatile and highly efficient manner. Its wide range of applications and its working principle make the 6N138WV opto-isolator an excellent choice for applications requiring noise rejections, circuit protection, and/or electrical isolation.
