Optoisolators - Transistor, Photovoltaic Output

HCPL-2533#300 is a readily available photovoltaic output transistor optoisolator by Avago Technologies, a semiconductor company headquartered in San Jose, California. It is designed to provide a sound level isolation between a low voltage logic signals (transmitter) and a device (receiver) working at a higher voltage. This optocoupler chip ensures that no interaction between the two will affect the signals sent.

How Does HCPL-2533#300 Work?

The HCPL-2533#300 optoisolator works by transforming a low-level signal to a higher level one through a series of processes. First, a primary light source, usually an infrared LED, illuminates a photo-sensitive Cell or Silicon Photodiode. The Light intensity is proportional to the current input voltage. The silicon photodiode then consumes the light energy and converts it into current or voltage to be used as a signal in the receiver circuit. The output signal and will rise with increasing light intensity.

Applications of HCPL-2533#300

The HCPL-2533#300 optoisolator is used in commercial, industrial and automotive switching power supplies, as well as a variety of signal modulating and control circuits. It can be found in almost any application where it is necessary to pass electrical signals across large distances with absolute reliability or with the transfer of data between dissimilar electronic systems. Other applications include medical instrumentation, battery-backed systems, communications equipment, computers, portable electronics, railway signaling and home automation.

Features of HCPL-2533#300

The HCPL-2533#300 is offer superior performance features such as a low input leakage current of 10nA (maximum), a low input session of 0.1V (typical), an output saturation voltage of 0.2V maximum and an AC or DC photocurrent transfer of 0.012mA (typical). It is available in two standard 8-leaded hermetically sealed surface mounted packages, (SMT DIP), and in 2-lead, 8-lead and 4-lead dual-in-line packages (DIP). Its low output saturation voltage and strict safety-compliance make it suitable for many industrial applications.
