Optoisolators, also known as optocouplers, are a form of electronic component that provides electrical isolation between two circuits using a LED light source, a phototransistor or a photodiode, or any combination of the three. The VOS615AT is a type of optoisolator from Vishay, specifically a transistor, photovoltaic output type.

The VOS615AT optoisolator uses an infrared emitting diode (IRED), optically coupled to a phototransistor, to provide a single-channel isolation. It is designed to increase system reliability and to reduce noise in signal transmission. The device features high temperature operation, maximum input dissipation, and a low collector-emitter saturation voltage.

An optoisolator transistor, photovoltaic output is used in a variety of applications that require electrical isolation between two or more circuits or components. It can be used as voltage transducers, contact less current switch, level and proximity detectors, couplers, and optical interfaces, to name a few. The VOS615AT is frequently used in DC motor control circuits, power inverters, and industrial process control systems. Additionally, this type of optoisolator is often used in the automotive industry as an alternative to increasing safety and reliability when controlling high voltage systems.

The VOS615AT optoisolator has a working principle based on the conversion of optical energy to electrical energy. The device contains a light source, usually an LED, that emits infrared radiation. This radiation is then absorbed by a phototransistor, which causes a current to flow in the transistor’s collector. The current will continue to flow until the LED is turned off or the current is interrupted. The current in the collector can then be used to control other circuits, such as relays, motors, or other devices.

The VOS615AT offers an isolation voltage of 2500Vrms, with a short circuit current of 100mA and a forward current of 50mA. It also features an automatic power shutdown, allowing for system reset and low power consumption. The optoisolator has an operating temperature range from -40°C to 125°C and is housed in a 4-lead, wide body, flat plastic package.

The VOS615AT optoisolator from Vishay is a transistor, photovoltaic output type optoisolator that has a variety of applications ranging from industrial process control systems to automotive voltage transducers. With its high temperature range and low collector-emitter saturation voltage, the device is particularly useful for high voltage DC motor control. The working principle of the VOS615AT is based on the conversion of optical energy to electrical current with an LED light source and phototransistor.
