Optoisolators are a type of galvanically isolated components designed to protect sensitive circuits from potentially harmful voltage. The EL816 series from OSI Optoelectronics is a line of optoisolators consisting of a transistor photovoltaic output. This particular optoisolator is fitted with an integrated photovoltaic chip, making it suitable for universal applications. It offers superior protection against high-voltage spikes, surge currents, and ESD.

The EL816 series optoisolators can operate over a wide voltage range of between 5 volts and 40 volts, with a peak-to-peak breakdown voltage of 140 volts. The operating temperature reaches between -40° C and 100° C, making it ideal for both indoor and outdoor applications. It also features a low turn-on voltage, a fast response time, and low power consumption. The optoisolator is also RoHS compliant and has been approved by UL, making it safe for use in any application.

The optoisolator series is commonly used in industrial, automotive, consumer electronics, and communications applications. Its integrated photovoltaic chip allows it to effectively isolate signals, making it suitable for applications such as power supplies, control systems, and data communication circuits. It is also used for portable and wearable devices, as its small size and low power consumption make it the perfect choice for this type of application.

The working principle behind the EL816 series optoisolator is relatively simple. When the LED light source is powered with an electrical current, it emits a light beam that is detected by the photovoltaic cell. The electrical current generated by the photovoltaic cell is then passed through the optoisolator\'s transistor output, allowing for a galvanic isolation between the two circuits. This isolation ensures protection against high-voltage spikes, surge currents, and ESD. The optoisolator also incorporates an internal clamp diode, which prevents the photovoltaic cell from being damaged by transient voltages.

In conclusion, the EL816 series optoisolators from OSI Optoelectronics are a reliable and cost-effective solution for applications ranging from industrial and automotive to consumer electronics and communications. This optoisolator series is equipped with an integrated photovoltaic chip and features a wide range of operating voltages and temperatures, as well as a fast response time and low power consumption. Its working principle is based on the photovoltaic effect, allowing it to effectively isolate signals and protect circuits from potentially harmful voltage. All of these features make the EL816 series optoisolator an ideal choice for any application.
