Optoisolators are a type of electrical component that provides electrical insulation between two circuits for the purpose of preventing one circuit from affecting the other. The basic principle is that a light source on one side of the device is used to generate an electrical signal in the other side. SFH6326-X007T optoisolator is typically used as a three terminal transistor, photovoltaic output IC produced using NUVISTOR technology developed by Siemens Semiconductors.

Application field of SFH6326-X007T

The SFH6326-X007T optoisolator is designed for signal switching, voltage isolation and noise protection. It is typically used as a line receiver to interface with logic devices that have low driver capability and also as a logic isolator that can isolate logic levels up to 1kV between logic gates and buses. It is also used to bridge logic outputs to an LCD interface.

The optic isolator can be used to help differentiate between digital signals and analog signals, allowing designers to create separate signal paths for each type. This is especially important in systems with low power components that would be affected by the power of digital signals. The optoisolator can also be used to reduce signal distortion, decrease noise, protect components from power surges, and prevent ground loops.

Working Principle of SFH6326-X007T

The SFH6326-X007T optoisolator uses a low-voltage LED to generate an electrical signal in the device’s photovoltaic output. The LED light passes through an optically isolated barrier, which converts the light into an electric current that can be used to switch a transistor on or off. The device uses a photoconductive output transistor which uses a photodiode to sense the light from the LED and control the flow of current through the transistor, allowing it to switch very quickly.

The optoisolator has three pins on the output side. The two outer pins are the high and low collector terminals and the middle pin is the emitter. The voltage on the input side of the device is passed through the LEDs and is then read through the photovoltaic output on the opposite side. When the LED is illuminated, the voltage drop across the photovoltaic output will be greater than when it is not illuminated. This allows the voltage on the output side to be used to control electronic circuits.

The SFH6326-X007T optoisolator is also designed to provide high electro-static discharge (ESD) protection. The device is designed to withstand up to 8KV of ESD, providing protection against high voltage surges. Additionally, the device is designed to be immune to electrical interference generated by radio frequency or other types of electromagnetic interference.

The SFH6326-X007T optoisolator provides an ideal solution for designers who need to interface low voltage digital signals with higher voltage power supplies, protection for sensitive components from power surges or other sources of interference and electro-static discharges. It is also an efficient and cost effective way to provide isolation between signals and logic devices.
