Optoisolators are components that are used to achieve electrical isolation between circuit nodes and are, therefore, a fundamental element of any noisy or high-voltage environment. The MCT62H transistor photovoltaic output (TPO) optoisolator is a popular example of a high-performance optoisolator ideal for use in a range of applications.

An optoisolator contains a radiation-emitting side, usually composed of an LED, and a radiation-receiving side, typically composed of a photodiode. The light that is emitted from the LED is directed onto a photodiode, which, in turn, then emits an electrical current at the output. The presence of this light is essential to the operation of an optoisolator, as the complete electrical isolation of the two circuits is only possible when the LED is active.

One of the most attractive features of the MCT62H optoisolator is its ability to operate in a broad range of temperatures. This is thanks to its high-temperature tolerance capabilities of up to 155°C, making it suitable for use in harsh conditions. Moreover, the device is constructed using an advanced High Temperature Epoxy (HTE) compound to ensure that the LED and photodiode materials remain stable and unaffected by the external environment. In addition, the optoisolator is UL and VDE approved, making it robust and reliable for a range of applications.

The MCT62H optoisolator’s operating principle is relatively simple. It consists of a six-pin package containing an LED, a photodiode, and a bipolar transistor. When current flows through the LED, it emits light which is directed to the photodiode. In response, the photodiode produces a photocurrent, and this causes the edges of the bipolar transistor to switch from on to off and vice versa. This switching action then causes the transistor to produce a corresponding electrical current at the output.

The MCT62H optoisolator’s applications can be found in a wide array of both commercial and industrial electronics, such as motherboards, motors, pumps, and power supplies. It can also be used for isolating AC and DC circuits, as well as for applications requiring redundancy and fault-tolerant operation. It is typically used in noisy environments, such as factories or workshops, where high voltages are present and electrical isolation is required. This device is also suitable for use in applications in which current needs to be passed through metal foils, such as those found in automotive and mobile equipment.

The MCT62H optoisolator is a robust and reliable device that is suitable for a range of applications. It uses an advanced HTE compound to ensure that its LED and photodiode components remain stable and unaffected by the external environment, making it a high-performance solution. Furthermore, it operates based on simple principles, whereby the light emitted by the LED causes the photodiode to emit a photocurrent, and this then switches the edges of the bipolar transistor to generate an electrical current at the output. The MCT62H is a powerful and efficient optoisolator that is capable of operating in a broad range of demanding commercial and industrial environments.
