Working Principle of H11A4TVM Optoisolator

The H11A4TVM optoisolator is a transistor-photovoltaic output device, which operates on the principles of electrical insulation and optical isolation. The optoisolator works by using a photovoltaic cell to convert an input electrical signal into an optical signal, which is then directed to a light-triggered transistor to produce an output electrical signal. The optoisolator isolates the input signal from the output signal, thus reducing the risk of interference and providing a high level of isolation.

The H11A4TVM optoisolator employs a unique dual output circuit to provide an output current of up to 300mA. The optoisolator features an LED driver on the input side which is used to drive the photovoltaic cell. This ensures that the output is triggered quickly and accurately by an electrical signal, while minimizing power consumption. To ensure that the optoisolator can operate at a wide temperature range, the temperature compensation circuit is employed on the transistor side to maintain stable output.
