Optoisolators, or optocouplers, are electrical components that act as information transfer devices used to isolate the input signal from the output signal in order to prevent cross-talk or even catastrophic failure of devices. This logic output optoisolator is the MOC5007TVM, an impressive device that offers 500Vrms for one minute of isolation between channels. It is also characterized by its low current transfer ratio (CTR) over a wide temperature range.

The application field of the MOC5007TVM is quite broad, being suitable for use in a variety of applications including: temperature and motor controls, relays (including LEDs in motor protection settings), switches, amplifiers, and other applications with high voltage isolation requirements. With its low power consumption, the device is also suitable for power line carrier communication, or any other related system.

MOC5007TVM optoisolator works based on the transfer of optical energy across the isolation barrier. The control terminal (CTRL) positioned on the left side of the device is connected to an input transistor. When the input signal is low, the transistor is activated, triggering the light-emitting diode (LED). The signal is then transferred to the optocoupler, where it is quickly converted into a current that passes through a reverse-biased diode. This converted electrical energy is then passed through the output control circuit, resulting in a logic level output at the output transistor (OUT).

The transfer characteristic of MOC5007TVM is one of its most advantageous features. It is characterized by its low CTR across wide temperature range as compared to other similar devices in the market, which makes the MOC5007TVM suitable for a variety of applications. The transfer curve of the device is illustrated as follows:

The MOC5007TVM optoisolator is also characterized by its high isolation voltage, which is advantageous for use in applications with potentially hazardous voltages. The device offers an isolation voltage of 500Vrms, which is enough to provide electrical and data isolation between channels. The device also provides additional isolation through its common-mode voltage protection of 8.5Vopen, 7.5Vclosen on high-end, as well as 45Vopen, 37Vclosen on low-end.

In addition, the MOC5007TVM optoisolator also offers a wide range of voltage regulation and integrated circuit protection features, which makes the device suitable for use in high-voltage systems. The device provides a wide common-mode transient immunity of 1500V, and ESD immunity of 8kV, which increases the system reliability even when in extremely high-power environments.

The MOC5007TVM logic output optoisolator is an excellent device for use in applications requiring high-voltage isolation and superior transfer characteristics. With its low-power consumption and simple design, the MOC5007TVM is a reliable device for any application requiring optical information transfer.
