K827PH

Optoisolators, also known as optocouplers, are electronic components which allow reliable data transfers across two independent electrically isolated circuits. The K827PH is a transistor-photovoltaic optocoupler, with both input and output circuits completely isolated from each other. Like any other optocoupler, it is used to ensure communication between two systems, while maintaining electrical safety and keeping RF interference and EMI away from the sensitive circuits.

At the core of the K827PH lies a high-efficiency GaAℓAs light emitting diode (LED). When a voltage source of 11 volts is applied, the LED excites and emits an infrared light which is detected by a photovoltaic output photocell placed directly behind the LED. Directly beneath the output photocell is a bi-directional thyristor, which is activated by the photon emission from the LED. A powered phototransistor completes the circuit, allowing for a low-power current flow when the connection is complete.

The K827PH offers a number of advantages to users over other optocoupler solutions. Its use of high-efficiency LED and photovoltaic technology make it significantly more efficient than other optocoupler solutions, reducing power dissipation and increasing current throughput. Additionally, its construction provides excellent temperature stability and galvanic insulation between input and output circuits. This ensures that both circuits are able to effectively communicate without interference from extraneous electrical noise.

The K827PH is a popular choice for a variety of applications, from motor control and interface logic to industrial automation systems. Due to its small size and exceptional performance, it is also popular for use in RF applications where it can be used to transmit data without introducing interference. Additionally, its high isolation voltage of 2000V makes it ideal for high voltage applications such as solar panel monitoring.

The K827PH provides an efficient and reliable way to transfer data between two circuits. Its high efficiency, temperature stability and insulation provide users with reliable transmission of signals without electrical noise or energy dissipation. Its versatile design makes it suitable for a variety of applications, from basic consumer electronics to industrial and RF applications. For engineers and designers looking for an optocoupler solution that fulfills their needs, the K827PH is an excellent option.
