Optoisolators, also known as optocouplers, are a type of electronic component that provides electrical and optical insulation between two connected circuits. The VO615A-1X017T optoisolator consists of a LED emitter and a photovoltaic detector. Its isolation voltage is 17kV peak, 1.0kV RMS, and it operates at a nominal input voltage of 5Vdc.

Application Field

The VO615A-1X017T optoisolator has a wide range of applications in the field of isolating voltage signals. It can be used to protect sensitive electronics on systems that require high voltage isolation. Furthermore, it can also be used in communication systems to transfer and transmit signals across circuits that must be kept electrically isolated. One of the most common uses of this optoisolator is in motor drives, where the isola-tion of the high voltage power supply from the logic control circuitry is essential for safety.

Working Principle

The VO615A-1X017T optoisolator is composed of an LED emitter and a photovoltaic detector. The LED emits light when a voltage is applied to its anode and cathode. The light reaches the photovoltaic detector and electro-magnetic radiation is generated. The generated signal is then amplified and regulated and then transmitted to the second connected circuit, which is electrically isolated from the first circuit.

The LED emitter, which is composed of a forward voltage diode, acts as a switch. When a voltage is applied across the anode and cathode of the LED, it turns on and starts emitting light. The intensity of the light is proportional to the current applied and the forward voltage across the LED. The photovoltaic detector converts the light into electrical energy, which is then amplified and regulated before being transmitted to the second connected circuit.

The VO615A-1X017T optoisolator also has an integrated shielding to minimize interference and noise from external sources, providing improved isolation performance while still being able to quickly switch signals. The shield also offers reliable operation even in harsh environments, such as high temperatures and shock and vibration applications.

To conclude, the VO615A-1X017T optoisolator is a versatile component that can be used in many applications to isolate voltage signals. It can be used to protect sensitive electronics in systems that require high voltage isolation, to transfer and transmit signals across circuits that must be kept electrically isolated, and also to provide reliable performance in harsh environments. The integrated shielding also provides improved isolation performance while still allowing for quick switching, making it an ideal choice for many applications.
