HCPL-7851#100 Application Field and Working Principle
Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps
The HCPL-7851#100 optocoupler is a 6-pin fibre optic device with an isolation distance of 3000Vrms (VDC). It consists of an 850 nm infrared light-emitting diode (LED) coupled with high speed integrated photodetector (VishayHCPL-7851#100). The device operates over a wide temperature range of -40°C to 85°C and is suitable for a variety of signal isolation applications.
HCPL-7851#100 can be used in a wide range of applications such as signal transmission, signal isolation, and power isolation in industrial, medical and automotive applications. It can also be used in low-noise amplifiers, signal conditioning, signal detection, and signal separation. The device\'s wide temperature range allows for reliable operation in extreme environments.
Working Principle of HCPL-7851#100
The HCPL-7851#100 works on the principle of opto-coupling. The optocoupler consists of a photodiode and an 885 nm infrared light-emitting diode (LED). When the LED is energized, it emits an infrared light which is then converted into electrical energy using a photosensitive material. This energy is then sent to a photodetector which amplifies the signal and finally sends it through the output pins on the device.
The working of HCPL-7851#100 is further divided into two stages. In the first stage, the LED emits infrared light and the integrated photodetector receives the same light and converts it into current proportional to the emitted radiation and changes the impedance across the device’s output pins. The second stage is the amplification stage. Here the signal is sent through an operational amplifier, which amplifies the current signal and increases its voltage.
Advantages of HCPL-7851#100
The HCPL-7851#100 optocoupler offers several advantages, making it ideal for a variety of applications. Some of the advantages include:
- High Isolation: The device offers 3000Vrms (VDC) isolation, which is higher than the 2000Vrms is offered by many other similar optocouplers.
- Low power dissipation: The device has low power dissipation, which makes it suitable for low-power applications.
- Wide temperature range: The HCPL-7851#100 optocoupler is designed to operate over a wide temperature range of -40 to +85°C, allowing for reliable operation in extreme temperature conditions.
- High speed: The device is designed to operate at a high speed of 1.5 Mbps.
- Available in a small package: The device is available in a small SOIC-6 package which helps in saving board space.
- Robust: The device is robust and highly reliable due to its high isolation and low power dissipation.
Applications of HCPL-7851#100
Due to its high electrical isolation, low power dissipation, wide temperature range and high speeds, the HCPL-7851#100 optocoupler is suitable for a variety of applications. Some of the applications of this device are as follows:
- Signal Isolation: The device is ideal for applications where signals have to be isolated from one another for safety reasons or to avoid interference.
- Power isolation: The high isolation of the device makes it suitable for isolating power in industrial, medical and automotive applications.
- Low-noise amplifiers: The device can be used for low-noise amplifiers as the low power dissipation reduces the noise generated by the device.
