Optoisolators are devices that provide isolation between two circuits using light. The main use of Isolators is to protect sensitive control circuitry form high-voltage or high-power devices that may be present on the other side of the circuit. The HCNW135-000E is a strobe-type optoisolator with a photovoltaic output. It is designed for general isolator applications such as industrial, process control, security systems, and medical electronics.

The HCNW135-000E is designed to to function as a transistor output on the receiving side of the isolator. It is in a 4-pin DIP package, with pin-outs 8 common cathode, 1 anode, 2 detector, and 4 emitter. When an input voltage is applied to the anode, a current flows through the LED inside the optoisolator which causes it to generate light that activates the photodetector. The photodetector converts the light back into an electrical signal, which is inverted with respect to its input on the anode. This inverted signal is then used as the output on the common cathode side of the isolator.

The HCNW135-000E also includes a phototransistor output, allowing it to be used as a photovoltaic device. In this configuration, the phototransistor is biased via a resistor connected between the emitter and the common cathode. A DC voltage is also applied to the emitter. When light passes through the phototransistor, it is converted to an electric current which causes a voltage drop across the resistor, and the phototransistor turns on. The voltage that is dropped across the resistor is then used as the output on the common cathode of the isolator.

The HCNW135-000E is a strobe-type optoisolator, which means that it is triggered by a short-duration pulse of light that is emitted from the LED inside the isolator. The photodetector then converts this light to an electrical signal and inverts it, producing an output on the common cathode side of the isolator. This type of isolator is ideal for applications that require a high-speed response, as the photodetector is able to respond very quickly to the light pulses from the LED.

The HCNW135-000E optoisolator is widely used in a variety of applications, such as industrial process control, security systems, and medical electronics. Its two outputs, transistor and photovoltaic, make it a versatile device that can suit a variety of needs. Its high-speed response time makes it an ideal choice for applications that require a quick response to stimuli.
