HCPL-817-30AE

HCPL-817-30AE application field and working principle

HCPL-817-30AE Optoisolators - Transistor, Photovoltaic Output are used in many critical applications, such as industrial controls, motor drives, and medical safety systems. These opto-couplers help to ensure reliability and provide data integrity by isolating the power, ground and logic subsystems of a system. The HCPL-817-30AE opto-couplers are designed to provide electrical and optical isolation to ensure these systems are safe in electrically noisy and hazardous environments.

The HCPL-817-30AE optoisolator consists of a light emitting diode (LED) and a phototransistor which are mounted in a single package. The LED is connected to the input of the optoisolator. The current through the LED is modulated by the input signal. The light emitted by the LED is detected by the phototransistor and turned into a current which is amplified and sent as an output signal.

The use of the optoisolator helps to isolate the input and output of electronic circuits, in order to provide higher levels of electrical isolation between the two. This helps to reduce the potential for interference and noise caused by the electrical environment. This makes the optoisolator ideal for applications which require high levels of electrical isolation, such as medical devices, industrial controls and motor drives.

The HCPL-817-30AE optoisolator has high isolation voltage up to 4,000 Vrms, as well as good common-mode and transient rejection. It has a guaranteed CTR of 50 to 500%, and a current transfer ratio (CTR) of 0.5 to 25%. The device has an operational temperature range of 0 to 70 °C.

The HCPL-817-30AE optoisolator is very reliable and well-suited for use in a variety of applications. It is designed to perform reliably in both extreme temperatures and high-voltage environments, making it an ideal choice for a wide range of industrial and medical applications.
