Optoisolators – Transistor, Photovoltaic Output are electric devices that use an opto-electronic technology to isolate two circuits electrically. The 6N135SDV is an example of such a device. It is used in sensor systems, industrial networks, embedded applications, and data communications.

At its core, the 6N135SDV consists of an LED driver and a phototransistor. Light from the LED is emitted and enters the phototransistor through an aperture. This light then causes current to flow between the collector and emitter of the phototransistor. This current flow is used to control the switching of the circuit and provides the basic isolation between the input and output circuits.

The 6N135SDV has several key features that makes it ideal for use in a wide variety of applications. First, it is linear over its entire input range, from 0.5mA up to 40mA, making it easy to interface with for various applications. Second, it has an internal hysteresis, which eliminates false triggering from noise. Finally, it includes an on/off delay which can be adjusted for applications that require precise switching timing.

In addition to the switching function, the 6N135SDV also features a short circuits protection that helps to protect the device from damage due to overload. This protection is provided by a current limit circuit that works by limiting the current that can be drawn from the output by the load. This current limit circuit is adjustable, allowing users to optimize the device for their specific application.

The 6N135SDV is primarily used in applications requiring optically isolated signal switching. Examples include signal switching in industrial networks, data communications, sensor systems, and embedded applications. It is also used in medical equipment where electrical insulation between electronics and patient is required. In these applications, the 6N135SDV provides a reliable and safe operation.

The main advantage of the 6N135SDV is its small size and low power consumption. The device is only 5mm x 5mm in size and uses minimal power, which makes it an ideal choice for applications that are size or power constrained. Additionally, the device also features a low output impedance which makes it ideal for use in high-speed and low-noise applications.

In conclusion, the 6N135SDV is an electrically isolated optocoupler with transistor-photovoltaic output. It has a linear input range, short circuit protection, and on/off delay to provide reliable operation in numerous applications. Its small size and low power consumption make it an ideal choice for applications that require an optically isolated signal switch.
