Optoisolators are devices that provide electrical insulation between two circuits while still allowing a signal to be transmitted between them. One particularly popular optoisolator is the HCNW138-000E, which provides galvanic isolation in a variety of applications that require an electrical contact between two otherwise isolated systems. In this article, we\'ll take a look at the HCNW138-000E\'s application field and working principle.

Application Field

The HCNW138-00E optoisolator has a variety of applications, but it is especially useful in medical fields such as medical imaging, patient monitoring, lab equipment, and diagnostics, all of which require electrical contact between two independent systems. Other applications include controlling, interrupting, and monitoring AC/DC current between consumer and industrial electrical systems. Additionally, the HCNW138-00E can be used to overcome difficulties associated with voltage overloads, surges, and circuit breakers.

Working Principle

The HCNW138-00E works by using a type of opto device known as a transistor-photovoltaic output (TPO). This is an optoisolator that features a light-emitting diode (LED) coupled to a photodiode and a transistor that are both mounted in a common package. The LED is driven by the input circuit, and the photodiode and transistor are connected to the output circuit. The photocurrent generated by the photodiode is used to bias the transistor to produce an isolated voltage output. The transistor can also be used to switch signals.

The HCNW138-00E optoisolator also has built-in protection for both the input and output circuits. Isolation is guaranteed up to 1000VRMS. Additionally, the device is designed to protect against overload, short-circuit, and high EMI/RFI environments.

In summary, the HCNW138-000E optoisolator is a reliable and versatile device that can be used in a variety of applications to provide galvanic isolation. Its working principle involves the use of a transistor-photovoltaic output, which allows signals to be transmitted between two circuits with electrical insulation. The built-in protection ensures that the input and output circuits are protected against overload, short-circuiting, and high EMI/RFI environments. With its reliable and versatile design, the HCNW138-000E optoisolator is well suited for use in various applications that require an electrical connection between two independent systems.
