6N135-020E

The 6N135-020E optoisolator is an integrated circuit designed to provide electrical isolation between two points. It utilizes transistor-photovoltaic-output (TPO) technology to safely and effectively protect sensitive electronics from electrostatic discharge (ESD). The device is primarily used in applications where ESD immunity and high noise isolation is required.

The 6N135-020E works by linking two isolated circuits via the light emitting diode (LED) and a Darlington transistor in a single package. The LED emits light when an electrical current is applied to it via one isolated circuit. The light is routed via a reflector and lens to the transistor, which is then activated when the light strikes. The transistor provides the driving current to activate the output circuit of the optoisolator through the second isolated circuit.

A distinguishing characteristic of the 6N135-020E is its very high noise rejection. This reduces the chance of excessive interference in the sensitive electronics that the TPO isolator is protecting by ensuring that only the signal intended reaches the output. Additionally, the 6N135-020E includes ESD protection for the input circuit.

The 6N135-020E has several applications including: AC and DC motor speed control, motor drive controllers, PC/PLC tachometer systems, temperature control systems, and machine vision systems. The 6N135-020E is a popular choice for applications where precise control of a motor or other device is needed, as it is very easy to set up and configure. It is also ideal for applications where ESD control is required or interference might damage sensitive electronics, as the high noise rejection helps to protect systems from interference.

In summary, the 6N135-020E optoisolator provides a reliable, easy to use, and low-cost method of isolating two circuits while providing noise isolation and ESD protection. Its wide range of applications makes it a popular choice for a variety of industries, and its simple setup and versatile design provide maximum flexibility for a wide range of applications.
