Optoisolators, which are also called optocouplers, are devices that are used to electrically isolate two sections of a circuit. They are commonly used in industrial and consumer applications where electrical noise is present, when there is a need for galvanic isolation to protect circuits from short circuits or damaging voltage spikes, and where it is necessary to filter signals to ensure accurate data communications. The H11B23S is a type of optoisolator that uses a transistor as its output type. It can be used in a variety of applications and has several unique features which make it ideal for use in circuit isolation and signal filtering.The H11B23S optoisolator utilizes a dual-emitter LED (light-emitting diode) as its input. This LED is connected to a floating photodiode and a collector base-emitter circuit that is attached to the output transistor. The LED’s emitted light is directed onto the photodiode, which then creates an impinging electrical current that is delivered to the base-emitter circuit. This current will turn on the output transistor.The optoisolator’s output transistor is a NPN type, meaning that it is a common emitter-type, with the output transistor’s collector being connected to the positive power source. The H11B23S can be used in several different types of applications, including circuits that require a high output voltage, as the output transistor is capable of handling voltages up to 60 V. It is also suitable for use in applications that need to filter or modify incoming signals, such as those used in power supply filters and audio and video applications. Additionally, the optoisolator can be used to isolate circuits that are subject to high interference.The H11B23S optoisolator’s photovoltaic output is capable of providing a low-noise, high-impedance signal. The circuit will also remain electrically isolated from the input and output terminals, providing improved safety to downstream circuits. Furthermore, the optoisolator has a wide galvanic isolation range (from 500VAC to 3.7kVAC). This helps ensure that the device can provide reliable isolation between circuits while remaining compliant with various safety regulations.The H11B23S optoisolator’s dual-emitter LED output also provides a high degree of reliability, due to its stable and linear transfer characteristics. This helps to ensure both correct and accurate signal transmission even in the presence of high levels of electrical noise, making it ideal for use in challenging applications. The optoisolator’s design is also able to withstand a wide range of operating temperatures, with temperatures ranging from -40°C to 100°C.In conclusion, the H11B23S optoisolator is a versatile and reliable device that is capable of providing both circuit isolation and signal filtering. It features a dual-emitter LED input and a photovoltaic output, which provide a low-noise, high-impedance signal. Additionally, the optoisolator is able to withstand a wide range of operating temperatures and has a wide galvanic isolation range. The optoisolator’s features make it suitable for a variety of applications, including those that require high output voltages or are susceptible to interference.
